Full textAbstract:
Non-intrusive appliance load monitoring is the process of disaggregating a household's total electricity consumption into its contributing appliances. In this paper we propose an approach by which individual appliances can be iteratively separated from an aggregate load. Unlike existing approaches, our approach does not require training data to be collected by sub-metering individual appliances, nor does it assume complete knowledge of the appliances present in the household. Instead, we propose an approach in which prior models of general appliance types are tuned to specific appliance instances using only signatures extracted from the aggregate load. The tuned appliance models are then used to estimate each appliance's load, which is subsequently subtracted from the aggregate load. This process is applied iteratively until all appliances for which prior behaviour models are known have been disaggregated. We evaluate the accuracy of our approach using the REDD data set, and show the disaggregation performance when using our training approach is comparable to when sub-metered training data is used. We also present a deployment of our system as a live application and demonstrate the potential for personalised energy saving feedback.

This paper presents disaggregation of appliances’ energy consumption for a residential house using Particle Swarm Optimization (PSO). The disaggregation process provides useful information about the time and duration of each appliance on when they are switched on, which can contribute to close monitoring of appliance activities in a house. Firstly, the data of aggregated electricity loads comprising six different appliances is measured and plotted based on total power (Ptotal) over time. The data is then formulated based on combinatorial optimization (CO) problem which represents the load disaggregation model that contains the sum power of all six appliances when they are switched on. The CO problem is solved by using PSO by setting up the population of particles to represent each appliance. The random number of each population is generated based on appliance’s power state when switched on, where the total appliances power (Papp) is represented as the sum of all six particles data. Thus, by using the known value of appliance on state as optimization boundary parameters, the CO problem is evaluated by PSO following the Integral Squared Error (ISE) minimization problem of Ptotal and Papp. The optimization results give good convergence criteria with accurate percentage of time taken for every appliance in use.

IoT has become an integrated part of our lives changing ways in which we operate our everyday appliances. In addition to making our home appliances smart, it has become a common trend for companies to adopt industry 4.0, which uses various sensors to monitor the equipment, machinery, and the work environment. We often come across multiple brands which make smart appliances but each brand comes with its separate mobile application for the appliance's operation. This requires us to switch between Apps to control these appliances if we at all remember which App controls which appliance. We intend to solve these two major inconveniences by creating a single mobile application that can control all these appliances using Augmented Reality technology. All we have to do is point our camera at the appliance that we need to operate and the App will display control options in real-time AR. This paper produces five important contributions: 1) An AR-based mobile application to control IoT devices and monitor the environment. 2) Implementing the mobile application using Unity 3D engine and Vuforia SDK. 3) Integrating a commercially available IoT device with the mobile application. 4) Integrating custom-made hardware IoT device with mobile application. 5) Integrating this combination to make our industries and homes smarter Keywords:

Full textAbstract:
Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. To describe the development of fixed functional appliances as well as our 20-year experience working with them. Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view in illustrating the different appliances. Rigid fixed functional appliances provide better skeletal results than flexible and hybrid ones. Flexible and hybrid appliances have similar effects to those produced by class II elastics. They ultimately correct class II with dentoalveolar changes. From a biomechanical standpoint, fixed functional appliances are more recommended to treat class II in dolichofacial patients, in comparison to class II elastics. The electromyographic (EMG) activity of masticatory muscles was monitored longitudinally with chronically implanted EMG electrodes to determine whether functional appliances produce a change in postural EMG activity of the muscles. Pre-appliance and post-appliance EMG levels in four experiments that had been fitted with functional appliances were compared against the background of EMG levels in controls without appliances. The insertion of two types of functional appliance to induce mandibular protrusion was associated with a decrease in postural EMG activity of the superior and inferior heads of the lateral pterygoid, superficial masseter, and anterior digastric muscles; the decrease in the first three muscles was statistically significant. This decreased postural EMG activity persisted for approximately 6 weeks, with a gradual return towards pre-appliance levels during a subsequent 6-week period of observation. Progressive mandibular advancement of 1.5 to 2 mm every 10 to 15 days did not prevent the decrease in postural EMG activity. KEY WORDS Orthodontics, Class II Malocclusion, Fixed Functional Appliance.

Full textAbstract:
A Removable functional appliance is composed of polished acrylic shields and stainless steel wires prescribed for patients with more pronounced class II malocclusion or open bite. These appliances work comfortably with a patient’s inherent growth to produce the desired Skeletal or Dental development. It can be achieved by dentoalveolar effects, alteration of soft tissue and utilisation of greater Mandibular growth potential. The commonly used Removable functional appliances are Twin Block appliance, Activator, Bionator, Frankel appliance, etc. This study aims to assess the frequency of the usage of removable functional appliances in a hospital based set up. The data of patients undergoing Removable functional appliance therapy was retrieved from the case sheets of the patients.The collected data was tabulated in Excel and statistically analysed with the help of SPSS software. From the results obtained, Twin block appliance was the most prevalent Removable functional appliance with a frequency of 60.6%. Frankel appliance and Activator each had a frequency of 9.1%. Twin block appliances were mostly preferred for males than females whereas Activator is preferred mostly for females. Based on the age, Twin block appliance was preferred for the age group 10-15 years, Frankel appliance for 5-10 years, Activator and Other appliances for 10-15 years. Therefore, within the limits of this study, we observed that Twin block appliance was the most preferred Removable functional appliance used in the management of Class II malocclusion and the most common age group receiving appliance therapy is 10-15 years.

ABSTRACT Objective: To explore the impact of fixed labial orthodontic appliances on speech sound production. Materials and Methods: Speech evaluations were performed on 23 patients with fixed labial appliances. Evaluations were performed immediately prior to appliance insertion, immediately following insertion, and 1 and 2 months post insertion. Baseline dental/skeletal variables were correlated with the ability to accommodate the presence of the appliances. Results: Appliance effects were variable: 44% of the subjects were unaffected, 39% were temporarily affected but adapted within 2 months, and 17% of patients showed persistent sound errors at 2 months. Resolution of acquired sound errors was noted by 8 months post–appliance removal. Maladaptation to appliances was correlated to severity of malocclusion as determined by the Grainger’s Treatment Priority Index. Sibilant sounds, most notably /s/, were affected most often. Conclusions: (1) Insertion of fixed labial appliances has an effect on speech sound production. (2) Sibilant and stopped sounds are affected, with /s/ being affected most often. (3) Accommodation to fixed appliances depends on the severity of malocclusion.

Full textAbstract:
The aim of the present study was to compare the area and volume of remaining cement after lingual and buccal multibracket appliance debonding. Further, the area and volume of cement remaining and the area and volume of enamel were also analyzed using a morphometric digital measurement technique. Ten buccal and 10 lingual multibracket appliances were cemented in 20 extracted teeth embedded into an epoxy resin model simulating a dental arch. The models were scanned before bonding the lingual and buccal multibracket appliances, after debonding the lingual and buccal multibracket appliances, and after polishing the remaining cement. Afterwards, the standard tessellation language (STL) digital files were aligned, segmented, and realigned by using engineer morphometry software. A comparative analysis was performed using Student’s t test statistical analysis. Lingual appliances showed statistically significantly (p < 0.001) less area (7.07 ± 4.85 mm2) and volume (0.87 ± 1.34 mm3) of remaining cement than the area (21.99 ± 4.18 mm2) and volume (p = 0.002) (3.48 ± 0.96 mm3) of buccal appliances. Moreover, lingual appliances showed statistically significantly (p = 0.001) less area (4.48 ± 3.08 mm2) and volume (0.13 ± 0.15 mm3) of remaining cement after polishing than the area (12.22 ± 5.98 mm2) and volume (p = 0.004) (0.70 ± 0.56 mm3) of buccal appliances. Lingual multibracket appliance therapy leads to less area and volume of cement remaining after multibracket appliance debonding and less area and volume of cement remaining after cement polishing than buccal multibracket appliance therapy; however, the area and volume of enamel removed after cement polishing were similar between both lingual and buccal multibracket appliance therapies.

Skeletal class II malocclusion is best treated by growth modification using the myofunctional appliances or the orthopedic appliances or the combination of the both depending upon the type of malocclusion encountered during the growth period of an individual. Though all myofunctional appliances work on the same principle with few basic differences; the orthodontist has to make a choice among the plethora of the appliances at his disposal. The present article is a case report of class II malocclusion treatment using the Bass appliance for the growth modification, which was followed by fixed appliance for the occlusal detailing.

Full textAbstract:
In the recent years, nonextraction treatment approaches and noncompliance therapies have become more popular in the correction of space discrepancies. One of the conventional approaches for space gaining in the arches without patient compliance is done by using certain extra oral appliances or intraoral appliance. The greatest advantage of certain appliances like fixed functional and molar distalization appliances is that they minimize the dependence on patient cooperation. Molar distalization appliances like pendulum appliance which distalizes the molar rapidly without the need of head gear can be used in patients as a unilateral space gaining procedure due to buccal segment crowding.

Full textAbstract:
Non-intrusive load monitoring, a convenient way to discern the energy consumption of a house, has been studied extensively. However, most research works have been carried out based on a hypothetical condition that each electric appliance has only one running state. This leads to low identification accuracy for multi-state electric appliances. To deal with this problem, a method for identifying the type and state of electric appliances based on a power time series is proposed in this paper. First, to identify the type of appliance, a convolutional neural network model was constructed that incorporated residual modules. Then, a k-means clustering algorithm was applied to calculate the number of states of the appliance. Finally, in order to identify the states of the appliances, different k-means clustering models were established for different multi-state electric appliances. Experimental results show effectiveness of the proposed method in identifying both the type and the running state of electric appliances.

Full textAbstract:
Currently, sustainability is considered a priority by society, with the household appliances being one of the economic sectors involved in achieving sustainability. However, the existence of several issues (e.g., energy and water consumption, reliability, initial cost, and illuminance, among others) together with the diversity of brands and models on the market, make the consumer’s decisions regarding sustainable options difficult, according to their concerns and related to each sustainability dimension (economic, environmental, and social). By combining evolutionary algorithms (EA) with multicriteria techniques, it is possible to achieve sustainable solutions for the consumer based on their requirements. In this paper, a method is presented to support the consumer by obtaining a set of sustainable household appliances on the market that suit their preferences, concerns, and needs. By using a case study to apply the approach developed here, a set of sustainable appliances from the market is obtained, where several benefits are achieved (e.g., energy and water consumption savings, avoidance of CO2 emissions) during the lifecycle of each appliance, chosen from the appliance’s industry.

Full textAbstract:
Background/Aim: Stabilization appliances have traditionally been used for the treatment of temporomandibular disorders and bruxism. The aim of this study was to evaluate the effect of two appliances (hard and soft) with different thicknesses on the electromyographic (EMG) activities of masseter and anterior temporalis muscles. Material and Methods: 30 healthy subjects have been divided into two groups of 15, according to the appliance material used (soft, hard). For each subject in both groups, two appliances have been prepared with 3 mm and 6 mm thickness. EMG recordings of bilateral masseter and anterior temporalis muscles were taken for each appliance. Results: The results showed that, the decrease in average EMG values during maximum voluntary clenching with a 3-mm and 6-mm-thick hard appliance was statistically significant compared with the average EMG of maximum voluntary clenching in the intercuspal position. The increase in average EMG values during maximum voluntary clenching with a soft appliance of 3 mm and 6 mm thickness was statistically significant. Conclusions: The hard stabilization appliances decrease the activity of the masseter and temporalis muscles, while the soft appliances increase the activity of the masseter and temporalis muscles.

Full textAbstract:
A critical review of the literature is presented covering the treatment of childhood thumbsucking habits using fixed intraoral habit appliances (hayrake, palatal crib). The habit appliances are classified into type and function. Data is tabulated for key references revealing the fragmented and distorted nature of the literature and its lack of consistency. A chronological approach is presented to confirm the confused and idiosyncratic character of the literature. Information is provided on the early work of Massler and Graber and the paradox of Mack, Komer and Reider. Haryett's seminal studies at the University of Alberta regarding aspects of the treatment used are critically reviewed. Reflections are presented on why Larsson's study,casting doubt on the wisdom of using habit appliances, continues to be ignored. The emergence of the Bluegrass Appliance is discussed in terms of its being a more humane appliance and the seeming reluctance of practitioners to apply it as a kinder form of appliance therapy. Information is reported on the pain and serious injuries inflicted on children by habit appliances. A comparison of the use of appliances in the USA is made with the UK, where fixed habit appliances are not popular. Concludes that fixed intraoral habit appliances are cruel and inflict pain and suffering on children out of all proportion to their necessity. Questions why these appliances continue to be used, implying that it could be a combination of financial inducement, professional insularity and the absence of concerted opposition from behavioral therapists.

Sleep apnea episodes represent a problem both for the patients and for the patient�s bed partners. The objective of this study was to record the comparative effects of two types of polymeric appliances in the therapy of some mild apnea symptoms (bruxism and snoring). The effect of therapy with the used appliances was pursued on 42 patients, divided in two groups. In the first group of 21 patients, we used a custom made appliance achieved by Erkoflex disks, and in the second group of 21 patients, the preformed SomnoFit�-Oscimed polymeric appliance. The survey lasted for a 12 month period, 1 month before the insertion in mouth of the appliances and 11 months therapy with polymeric appliances. The authors� questionnaire was completed daily by the patients and their bed partners, which noted the night comfort with inserted appliances in the mouth, the existence/absence of morning pain in the area of the masseter muscle, existence/absence of the morning fatigue, respectively the maintaining, diminishing and the absence of snoring and of nocturnal bruxism. The results of the study were favorable and proved that the nocturnal therapy of bruxism and of snoring, by using these two polymeric appliances were efficient. SomnoFit� appliance performed better in reducing bruxism and snoring, but custom made Erkoflex appliances presented a greater resistance in time.

ABSTRACT Objective To evaluate the perception of esthetic orthodontic appliances by means of eye-tracking measurements and survey investigation. Materials and Methods En face and close-up images with different orthodontic appliances (aligner appliance [a], aligner appliance and attachments [b], lingual appliance [c], ceramic brackets [d], no appliance [e; control]) were shown to 140 participants. Eye movement and gaze direction was recorded by eye-tracking system. For different anatomical areas and areas of the appliances, time to first fixation and total fixation time were recorded. The questions included in a visual analog scale regarding individual sentiency were answered by the participants. Results For all groups, the anatomical landmarks were inspected in the following order: (1) eyes, (2) mouth, (3) nose, (4) hair, and (5) ears. Only in group d, first fixation was on the mouth region (1.10 ± 1.05 seconds). All appliances except the lingual appliance (1.87 ± 1.31 seconds) resulted in a longer fixation on the mouth area (a, 2.97 ± 1.32 seconds; b, 3.35 ± 1.38 seconds; d, 3.29 ± 1.36 seconds). For close-up pictures, the fastest (0.58 seconds) and longest (3.14 seconds) fixation was found for group d, followed by group b (1.02 seconds/2.3 seconds), group a (2.57 seconds/0.83 seconds), and group c (3.28 seconds/0.05 seconds). Visual analog scale scoring of questions on visibility were consistent with eye-tracking measurements. With increasing visibility, the feeling of esthetic impairment was considered higher. Conclusions Lingual orthodontic appliances do not change how the face is perceived. Other esthetic orthodontic appliances may change the pattern of facial inspection and are different in subjective perception.

Objective: To compare young people’s experiences of wearing a range of orthodontic appliances. Design: A cross-sectional, qualitative study with purposive sampling. Setting: UK dental teaching hospital. Participants: Twenty-six orthodontic patients aged 11–17 years. Methods: Patients participated in in-depth semi-structured interviews. All interviews were transcribed verbatim and analysed thematically. Results: Young people reported physical, practical and emotional impacts from their appliances. Despite these reported impacts, participants described ‘getting used’ to and, therefore, not being bothered by their appliance. Framework analysis of the data identified a multi-dimensional social process of managing everyday life with an appliance. This involves addressing the ‘dys-appearance’ of the body through physically adapting to an appliance. This process also includes psychological approaches, drawing on social networks, developing strategies and situating experiences in a longer-term context. Engaging in this process allowed young people to address the physical, practical and emotional impacts of their appliances. Conclusion: This qualitative research has identified how young people manage everyday life with an appliance. Understanding this process will help orthodontists to support their patients.

Full textAbstract:
In this work, an Appliance Scheduling-based Residential Energy Management System (AS-REMS) for reducing electricity cost and avoiding peak demand while keeping user comfort is presented. In AS-REMS, based on the effects of starting times of appliances on user comfort and the user attendance during their operations, appliances are divided into two classes in terms of controllability: MC-controllable (allowed to be scheduled by the Main Controller) and user-controllable (allowed to be scheduled only by a user). Use of all appliances are monitored in the considered home for a while for recording users’ appliance usage preferences and habits on each day of the week. Then, for each MC-controllable appliance, preferred starting times are determined and prioritized according to the recorded user preferences on similar days. When scheduling, assigned priorities of starting times of these appliances are considered for maintaining user comfort, while the tariff rate is considered for reducing electricity cost. Moreover, expected power consumptions of user-controllable appliances corresponding to the recorded user habits and power consumptions of MC-controllable appliances corresponding to the assigned starting times are considered for avoiding peak demand. The corresponding scheduling problem is solved by Brute-Force Closest Pair method. AS-REMS reduces the peak demand levels by 45% and the electricity costs by 39.6%, while provides the highest level of user comfort by 88%. Thus, users’ appliance usage preferences are sustained at a lower cost while their comfort is kept impressively.

Currently, wide arrays of fixed functional appliances are available for the correction of Class II malocclusion. The orthodontist must choose from these appliances depending on the mechanics, efficiency, and cost of the appliance. Fixed functional appliances may reduce the individual visits and hence the cost as compared to the removable appliances. Additionally, it may save the clinician’s chair time. This report discussed the in-house laboratory fabrication and clinical procedure of customized fixed functional appliances by utilizing the readily available dental materials in the orthodontic clinical setting.

Abstract Objective: To evaluate the anteroposterior short-term skeletal and dental effects on Class II malocclusion in growing patients following treatment with functional appliances (activators or twin block), extraoral traction, or combination appliances (appliances with both functional and extraoral traction components), based on published data. Materials and Methods: A literature search was carried out identifying a total of nine prospective clinical trials. The data provided in the publications underwent meta-analysis using the random effects model with regard to SNA, SNB, ANB, and overjet. Results: All appliance groups showed an improvement in sagittal intermaxillary relationships (decrease in ANB) when compared to untreated subjects. Activators and twin block appliances accomplish this mainly by acting on the mandible (increases in SNB) while twin block appliances also seem to act on the maxilla (decrease in SNA). Extraoral traction appliances achieve this by acting on the maxilla (decreases in SNA). Combination appliances mainly act on the mandible (increase in SNB). Activators, twin block, and combination appliances also reveal a decrease in overjet, which is not the case in the singular use of extraoral traction. Conclusions: Intermaxillary changes being present in all appliance groups, anteroposterior treatment response following the use of functional appliances and/or extraoral traction in growing class II malocclusion patients is most evident in one of the two jaws (mandible for activators and combination appliances and maxilla for extraoral traction) except for the twin block group, which shows changes on both jaws.

A core aim in stoma care is to ensure the appliance (also known as a pouch or bag) establishes and maintains a secure seal, and so identifying the appropriate appliance for an individual ostomate is vital. This article presents a summary of the latest available range of stoma appliances on the market. There are two types of pouching systems: one and two piece. There are three main types of stoma appliances: closed, drainable and urostomy. Stoma care nurses need to be well informed about stoma appliance innovation, so that they can advise patients on what appliance is best for them. It is also the role of a stoma care nurse to educate patients on the technique for appliance application. If a patient is wearing an inappropriate appliance or they have a poor application technique, this can result in stoma complications, such as leakage and/or sore peristomal skin.

Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, scheduled for conventional orthodontic treatment, served as a study subject. After a precise clinical and radiographic examination, the approach was to digitize the patient’s dental arches and then to correct them virtually by computer. Additive manufacturing was then used to fabricate a mould for a soft customized appliance. The mould was manufactured using stereolithography from Somos ProtoGen O-XT 18420 material. Casting material for the mould to obtain the final appliance was silicone. As a result we managed to create a customized soft orthodontic appliance. Also, the accuracy of the method was found to be adequate. Two versions of the described device were manufactured: one with small and one with moderate orthodontic force. The study person also gave information on the subjective patient adaptation aspects of the oral appliance.

AbstractTo support a rational and efficient use of electrical energy in residential and industrial environments, Non-Intrusive Load Monitoring (NILM) provides several techniques to identify state and power consumption profiles of connected appliances. Design requirements for such systems include a low hardware and installations costs for residential, reliability and high-availability for industrial purposes, while keeping invasive interventions into the electrical infrastructure to a minimum. This work introduces a reference hardware setup that allows an in depth analysis of electrical energy consumption in industrial environments. To identify appliances and their consumption profile, appropriate identification algorithms are developed by the NILM community. To enable an evaluation of these algorithms on industrial appliances, we introduce the Laboratory-measured IndustriaL Appliance Characteristics (LILAC) dataset: 1302 measurements from one, two, and three concurrently running appliances of 15 appliance types, measured with the introduced testbed. To allow in-depth appliance consumption analysis, measurements were carried out with a sampling rate of 50 kHz and 16-bit amplitude resolution for voltage and current signals. We show in experiments that signal signatures, contained in the measurement data, allows one to distinguish the single measured electrical appliances with a baseline machine learning approach of nearly 100 % accuracy.

Class II malocclusion is one of the most commonly occurring conditions, and the component mostly involved is mandibular retrognathism. The treatment modalities include both removable and fixed appliances. The advantage of fixed functional appliances is that it is not dependent on patient compliance. Various fixed functional appliances are available such as rigid, flexible, and hybrid. The present case series discusses a hybrid type of fixed functional appliance, i.e. Twin Force Bite Corrector appliance in three cases: A 15‑year‑old female patient with Class II malocclusion due to mandibular retrognathism, a 14‑year‑old male patient with Class II malocclusion due to mandibular retrognathism, and a 14‑year‑old female patient with Class II malocclusion due to mandibular retrognathism. The effects produced by this appliance are similar to the conventional fixed functional appliances such as Forsus, Herbst, and also it has a distinct advantage of quick chair-side fabrication and simple design.

Increasing environmental concerns have resulted in consumers indulging in conserving energy by curtailing energy usage rather than switching to energy efficient practices. Energy efficient appliances (EEAs) offer the dual advantages of appliance usage with reduced energy consumption. Research suggests that use of such appliances, in residences is limited. This study was thus undertaken to understand individual resident's awareness towards EEAs and factors influencing their purchase. A qualitative approach consisting of 31 personal interviews were conducted with individuals from socio-economic categories A1, A2 and B1. While awareness of EEAs was present among respondents; benefits of using such appliances were neither widely known nor easily quantifiable. Purchase decisions were ruled by appliance price but did not deter adoption, the availability of appliances in desired aesthetics and family involvement in purchase decision. Higher penetration of such appliances can be ensured if consumers can estimate exact savings in monthly electricity bills due to EEAs at the time of purchase.

Full textAbstract:
In the process of orthodontic treatment, root parallelism is related to the relapse of extraction spaces, black triangles, and periodontal health. However, there are few studies on root parallelism in extraction cases with different types of appliances. The objective was to compare the root parallelism in extraction cases treated with clear aligners vs. those treated with fixed appliances by measuring the differences per extraction site and to access the root-movement control capacity of both orthodontic appliances. A retrospective study was conducted on cases in which the first premolars were extracted, treated by clear aligner appliance (“Invisalign” system, 28 patients) or fixed appliance (30 patients). The angulations of the tooth axis (canines, the second premolars, the first molars, and the second molars) were measured to analyze and compare the difference in root parallelism between the two orthodontic appliances. The percentage of root parallelism between the canine and second premolar in both groups had no significant difference. However, judging from the average angle difference value, the fixed appliance might have a greater range in root angulation adjustment than the aligner. In the angulation categories, the aligner mainly showed root apical divergence, while the fixed appliance mainly showed root apical convergence. The dental crown of the molars was mainly non-tipping in both groups, but it could be observed that the dental crown of the maxillary molars had a tendency toward mesial inclination. In conclusion, the same root parallelism and root inclination were obtained in tooth extraction cases whether treated by clear aligners or fixed appliances. This study provides clinicians with more information on the performance of clear aligners and fixed appliances.

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.

Abstract Objective: To assess the prevalence, intensity, and extent of the impacts on daily performances related to wearing different types of orthodontic appliances. Materials and Methods: A total of 1657 students, 15 to 16 years old, were randomly selected from those attending all secondary schools in Bauru, São Paulo, Brazil. Only those wearing orthodontic appliances at the time of the survey were included. Face-to-face structured interviews were done to collect information about impacts on quality of life related to wearing orthodontic appliances, using the Oral Impact on Daily Performances (OIDP). Adolescents were also clinically examined to assess the type of orthodontic appliance they were wearing. Comparisons, by type of orthodontic appliance and covariables, were performed using nonparametric statistical tests. Results: Three hundred fifty-seven adolescents (36.1% boys and 63.9% girls) undergoing orthodontic treatment participated in the study. The prevalence of condition-specific impacts related to wearing orthodontic appliances was 22.7%. Among adolescents with impacts related to wearing orthodontic appliances, 35.8% reported impacts of severe or very severe intensity and 90.1% reported impacts on only one daily performance, commonly eating or speaking. The prevalence, but not the intensity or the extent, of condition-specific impacts differed by type of orthodontic appliance (P = .001). Conclusions: One in four Brazilian adolescents undergoing orthodontic treatment reported side effects, specific impacts on daily living, related to wearing orthodontic appliances. Such impacts were higher among adolescents wearing fixed rather than removable or a combination of fixed and removable orthodontic appliances. This information could help to inform patients about the frequency and intensity of sociodental impacts during the course of their treatment.

The purpose of this study was to evaluate the skeletal and dentoalveolar effects and optimal timing for treatment of class II malocclusion with functional appliances in children and adolescents.A group of 30 patients with class II malocclusion were divided into 3 groups according to their use of functional appliance: Twin block, Activator, Fränkel appliance. The group was also divided into 2 groups according to the cervical vertebrae maturation method. Lateral cephalometric radiographs were analyzed pretreatment (T0) and posttreatment (T1). Among the functional appliances, treatment with Twin block and Activator showed significant increase in the length of the mandible (Co-Gn) and the lower anterior facial height (ANS to Me), whereas the overjet and overbite were significantly reduced. Treatment with Fränkel appliance showed significant improvement in the relationship of maxilla and mandible. In addition, if the functional appliance was used during the period of pubertal growth peak, there was a significant increase in mandibular length, improvement in the relationship of maxilla and mandible, labial inclination of lower incisors and decrease in overjet compared to the treatment before pubertal growth peak. Therefore, this study indicates that using functional appliances for patients with class II malocclusion is effective and the optimal timing for using functional appliances is during pubertal growth peak.

Non-Intrusive Load Monitoring (NILM) increases awareness on user energy usage patterns. In this paper, an efficient and highly accurate NILM method is proposed featuring condensed representation, super-state and fusion of two deep learning based models. Condensed representation helps the two models perform more efficiently and preserve longer-term information, while super-state helps the model to learn correlations between appliances. The first model is a deep user model that learns user appliances usage patterns to predict the next appliance usage behavior based on past behaviors by capturing the dynamics of user behaviors history and appliances usage habits. The second model is a deep appliance group model that learns the characteristics of appliances with temporal and electrical information. These two models are then fused to perform NILM. The case study based on REFIT datasets demonstrates that the proposed NILM method outperforms two state-of-the-art benchmark methods.

With the emergence of the smart grid environment, smart meters are considered one of the main key enablers for developing energy management solutions in residential home premises. Power consumption in the residential sector is affected by the behavior of home residents through using their home appliances. Respecting such behavior and preferences is essential for developing demand response programs. The main contribution of this paper is to discover the association between appliances’ usage through mining temporal association rules in addition to applying the temporal clustering technique for grouping appliances with similar usage at a particular time. The proposed method is applied on a time-series dataset, which is the United Kingdom Domestic Appliance-Level Electricity (UK-DALE), and the results that are achieved discovered appliance–appliance associations that have similar usage patterns with respect to the 24 h of the day.

In this twenty first century, man is exposed to a very high amount of magnetic fields in his environment. This is mainly due to the ubiquitous use of electricity and other technological devices, which are the major sources of magnetic field pollution. The effect of magnetic field exposure on health problems and safety risk of people is continually being investigated. A number of international organizations have formulated guidelines on limits to the value of the generated magnetic field. This work provides information on the amount of 50 Hz magnetic field created by some common home electrical appliances, and compare results obtained with permissible exposure limit by The International Commission on Non-Ionising Radiation Protection (ICNIRP) for the public. The home electrical appliances investigated include electric cooker, hair dryer, toaster, kettle, fan, microwave oven, electric iron, voltage stabilizer, etc. Measurements were carried out with the aid of a magnetic field strength meter, at a distance of 3 cm to 75 cm from the appliances. Results showed that the magnetic field varies with distance from the appliances (by quarter of a meter, most become negligible), the power consumption of the appliance, the age of the appliance, and the product (manufacturer) of the appliance. Also, appliances with electromagnets, coils and electric motors produce more magnetic fields than appliances with heating elements. At a distance of 3 cm from the appliances, the highest value of magnetic field obtained was 85.5 µT and the lowest value of the magnetic field obtained was 4.28 µT. The overall results obtained indicate that the magnetic field strengths are lower than the maximum permissible exposure limit (100 µT) recommended by ICNIRP for members of the public, and therefore, will not lead to any significant exposure risk. In conclusion, in-expensive measures of reducing magnetic field exposure are recommended.

ABSTRACT Objective: To compare patients’ perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Material and Methods: Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results: Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions: The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended.

Abstract Objective: To evaluate the impact of psychological traits on patients' choice of orthodontic appliances and their adjustability to orthodontic treatment. Materials and Methods: The sample consisted of 68 adult patients divided into three groups (28 buccal, 19 lingual, and 21 clear aligners). Prior to treatment participants filled out the Brief Symptom Inventory to assess symptoms of mental distress and the Narcissistic Vulnerability Scale to assess narcissistic personality traits. During the first week after appliance delivery and on day 14, patients completed a Health-Related Quality of Life questionnaire to assess their perception of pain and four areas of dysfunction. The correlation between personality traits and patients' reaction to treatment was evaluated. Results: Somatization was the only trait that affected the choice of lingual and clear aligner appliance. Reduced self-esteem regulation was associated with increased pain in all patients, while exploitation was associated with pain in lingual patients. Narcissistic vulnerability slightly influenced patients' adaptability to orthodontic appliances. Although adjustability to lingual appliances was the most difficult, only two parameters were affected by personality features. In the buccal group, adjustability was affected by numerous parameters. Adaptation to the clear aligner appliance was relatively uneventful and least affected by psychological features. Conclusion: Anxious individuals tend to prefer lingual and clear aligner appliances. The selection of lingual and clear aligner appliances governs the patient's response and recovery process, leaving little room for the effect of psychological features. On the other hand, the buccal appliance allows for greater impact of personality traits on adjustability.

Full textAbstract:
Treatment of complex malocclusion poses a challenge for the orthodontist because of its multifactorial aetiology. Class II malocclusion is the most frequently encountered and treated malocclusion in orthodontic practice and affects approximately 14.6 % of the North Indian population.1 A common reason for Class II malocclusion is mandibular skeletal retrusion which is the most common characteristic, as reported by McNamara.2 This can be caused by genetic or hereditary factors. When evaluating treatment options for Class II patients, the extent of the skeletal discrepancy and the skeletal maturity of the patient needs to be considered. Treatment may range from dental compensation including camouflage with extractions to surgical procedures targeted at moving the jaw at fault. In growing patients, growth modification with functional appliances offers an intermediate treatment option. Functional appliances are basically of two types; Removable and Fixed. Removable functional appliances such as Activator, Bionator, Frankel Function regulator and Twin Block appliance change Class II relationship by the transmission of soft tissue tension to the dentition. Treatment success with these appliances relies heavily on patient compliance. Therefore, in non-compliant patients, fixed Class II correctors in conjunction with fixed orthodontic appliances are the best choice.3 Fixed functional appliances generate continuous stimuli for mandibular growth without break and permit better adaptation to functions like mastication, swallowing, speech and respiration.1 The Herbst fixed functional appliance has been used routinely for Class II patients and has undergone many design variations over time.4 The AdvanSync2 Class II corrector is a recently introduced fixed functional appliance. It has a much smaller size than the conventional Herbst appliances, is easier to place, activate and remove and most importantly, can be used in conjunction with full-arch fixed appliances throughout.3 Here we describe a case report of a patient treated with the AdvanSync2 Class II corrector and the findings observed in the sagittal and vertical dimensions

OBJECTIVE: To evaluate the esthetic perception of different appliances by Brazilian lay adults and its influence in the attributed value of orthodontic treatment, considering evaluators' socioeconomic status, age and gender. METHODS: Eight different combinations of orthodontic appliances and clear tray aligners were placed in a consenting adult with pleasing smile. Standardized frontal photographs were captured and incorporated into a research album. A sample of adults (n = 252, median = 26 years old) were asked to rate each image for (1) its attractiveness on a visual analog scale and (2) the willingness to pay (WTP) for a cosmetic appliance when compared to a standard metalic appliance and a clear tray aligner. Comparisons between the appliances' attractiveness were performed using the Friedman's test and Dann's post-hoc test. Correlation between appliances' attributed value, socioeconomic status, age, gender, and esthetic perception was assessed using Spearman's correlation analysis. RESULTS: Attractiveness ratings of orthodontic appliances varied significantly in the following hierarchy: Clear aligners>sapphire brackets>self-ligating/conventional stainless steel brackets>and golden metal appliances. The correlation between WTP and esthetic perception was week. However, for individuals with better socioeconomic status and aged between 17-26 years old significantly, a significantly higher WTP was found. CONCLUSION: Clear aligners and sapphire brackets with esthetic archwire were considered better esthetic options in this sample. Nevertheless, patients were not willing to pay more money for appliances they deemed more esthetic, however, they were significantly influenced by their socioeconomic level and age.

Full textAbstract:
Wireless Sensor Networks (WSNs) is a composition of tiny self-operated devices that communicate with other devices in an ad-hoc fashion. WSNs find its application in real-time appliances due to its cost effectiveness and ease of deployment nature. Energy preserving in these networks while extending its support for real-time appliances is vital so as to preserve the operating hours of the system. To perform an energy efficient operation of WSN devices integrated with real-time appliances, a mutually cooperative and monitoring model is preferred. Depending on the Behavior of Utilization (BoU), energy allocated for each appliance can be shared in a distributed manner with the other appliances to cope-up with the energy constraints and improve prolonged operation. With forehand information about the operating device and its nature towards energy requirement, the energy allocation can be decided over a multi-state operative function to make a decision. The decision making follows Markov-Chain Model (MM) to make decisions between the operation states of an appliance. The outcome of the decision model will result in admitted operation time and energy conservation of an appliance.

Full textAbstract:
This paper describes the pattern of electricity consumption from total and selected domestic appliances at a typical terrace house in Malaysia. The measured appliances can be classified into four groups on the basis of pattern of use which are ‘standby’ (TV), ‘active’ (massage chair, charger of hand phone, laptop and power bank, washing machine, air-conditioners, iron, standing fan, shower heaters, rice cooker, toaster, microwave), ‘cold’ (refrigerator) and ‘cold and hot’ (water dispenser). The major contribution of monthly electricity consumption comes from ‘cold’ appliances that consume 118.8 kWh/month followed by ‘active’ appliances that consume 87.8 kWh/month and ‘cold and hot’ appliance with 52.5 kWh/month. ‘Standby’ appliances shown a small contribution to the total electricity with 0.9 kWh/month. The amount of energy consumed depends on time-of-use, power characteristics of particular appliances as well as occupancy period.

Objective : Overjet is a horizontal relationship between maxillary and mandibular incisors. Normal range from overjet is 2-4 mm. Increased overjet is marked by maxillary incisor’s protrusion. A 6 mm overjet will have impact on psychological and social relationship of children due to the aesthetics of the face profile. Increased overjet has relationship with Class II Angle malocclusion, Class II skeletal sagittal relationship, and mandibular retrognathia. Clinical problem caused by increased overjet in children are maxillary permanent incisors trauma in growing age, damaged periodontal tissue, lip incompetency, social impact such as lack of confidence in children, and also increased overjet has a close relationship with Temporomandibular Disorder (TMD) sign and symptoms.Methods : Increased overjet case can be managed by maxillary retraction of labial segment and increasing mandibular labial segment. Case management are based on skeletal and soft tissue pattern and patient’s age. Reducing overjet can be based on using several appliances, such as functional removable appliance to modify dental and skeletal relationship, fixed orthodontic appliances with tipping and bodily movement or using jaw reposition by orthognathic surgery.Results : One of the effective appliance to reduce overjet, especially Class II malocclusion treatment is Twin Block Functional Appliances developed by Clark. Twin Block appliances is used for developing age children in certain time period to support mandibular growth. This appliance is easy to use, so the patient cooperativity can be maintained. Maximum treatment depends on children’s cooperativity. By using Twin Block functional appliance, we can observe that early treatment can be effective to reduce overjet, to change skeletal pattern, and to increase children psychology such as self-confidence by making aesthetic changes to their faces significantly.[B1] Conclusion : This appliances is made with 70o angle to occlusal plane. Maxillary arch lateral expansion can be achieved with expansion screw. Patient will be instructed to use the appliance for 24 hours a day.[B2]

Abstract With rationalization of electricity consumption, it is possible to obtain savings of electric energy in households, as well as financing and capital input for the electricity production. Rational use of appliances in the best operating modes can reduce the final consumption of electricity, representing a positive impact on improving the environment quality. The main objective of this paper was to measure the electricity consumption of appliances in various operating modes. The measured values from two energy suppliers were recorded and processed in tables and figures, from which we created a table of the financial costs necessary for operation of appliances in different modes. For the calculation of annual electricity consumption and electricity prices, an application allowing selection of individual products from suppliers with current electricity prices was designed. According to the tables of electricity prices, various modes of appliance operation allow the selection of the most preferred mode for appliance operation based on the lowest price, rational consumption and energy costs. The aim of the paper is to demonstrate the consumption and costs of operating appliances in certain operating modes, standby modes and their efficient use or functionally similar appliances for reduction of electricity consumption in households.

Full textAbstract:
Non-intrusive load monitoring (NILM) is a fast developing technique for appliances operation recognition in power system monitoring. At present, most NILM algorithms rely on the assumption that all fluctuations in the data stream are triggered by identified appliances. Therefore, NILM of identifying unidentified appliances is still an open challenge. To pursue a scalable solution to energy monitoring for contemporary unidentified appliances, we propose a voltage-current (V-I) trajectory enabled deep pairwise-supervised hashing (DPSH) method for NILM. DPSH performs simultaneous feature learning and hash-code learning with deep neural networks, which shows higher identification accuracy than a benchmark method. DPSH can generate different hash codes to distinguish identified appliances. For unidentified appliances, it generates completely new codes that are different from codes of multiple identified appliances to distinguish them. Experiments on public datasets show that our method can get better F1-score than the benchmark method to achieve state-of-the-art performance in the identification of unidentified appliances, and this method maintains high sustainability to identify other unidentified appliances through retraining. DPSH can be resilient against appliance changes in the house.

Abstract : Treatment of class II malocclusion often require maxillary molar distalization. Some of the cases can be treated by non-extraction treatment modalities such as headgear, removable appliances, and intraoral distalizers such as the Pendulum appliance, Distal Jet, and Jones Jig. Anchorage loss from proclination of anterior teeth, distal tipping and increased overjet are major concerns with most of these appliances; some also require active patient compliance22.
