Abstract:
Abstract An experiment was conducted to determine the optimal dietary concentration of standardized total tract digestible (STTD) Ca for growth and feed efficiency of nursery pigs. A total of 2,185 pigs (initial BW =11.2 ± 1.4 kg) were blocked according to BW and randomly allotted to 1 of 6 dietary treatments, with STTD Ca formulated to 0.38, 0.46, 0.54, 0.62, 0.70, or 0.78% by increasing dietary limestone at the expense of corn. Each treatment had 16 replicate pens with 23 pigs per pen. Corn and soybean-based diets were formulated to contain 0.36% STTD P, which exceeds NRC 2012 (+9%). This resulted in STTD Ca: STTD P ranging from 1.1 to 2.2. To minimize variation, 2 basal diets were produced (0.38 and 0.78% Ca diets), and then blended on site to produce the intermediary levels. Data were analyzed using the MIXED procedure of SAS (Cary, NC) with fixed effect of diet and random effect of block. Prediction equations were generated using the FITTED GROUP of JMP with goodness of fit techniques to optimize the R2 value and RMSE. Feed conversion ratio (FCR) declined linearly (P = 0.011) with increasing levels of STTD Ca in the diet, and is described by: FCR = [1.456 + (0.115 x STTD Ca)] (R2 = 0.698, RMSE = 0.013). Final pig weight tended to increase (quadratic, P = 0.110) as dietary STTD Ca increased, and is described by: BW = [22.77 – (0.55 x STTD Ca) – (7.72 x (STTD Ca – 0.58)2] (R2 = 0.696, RMSE = 0.135). Exceeding 0.70% STTD Ca (2.0:1.0 STTD Ca: STTD P) reduced pig growth, FCR, and profitability. Adequate STTD Ca levels ranged from 0.46 to 0.62% (STTD Ca:STTD P, 1.3 to 1.8), but growth and profit were optimized at 0.54% (1.5:1.0 STTD Ca: STTD P).

Abstract:
Abstract A total of 2,184 pigs (initially 12.4 kg) were used to evaluate effects of varying analyzed Ca:P ratios at 2 levels of standardized total tract digestible (STTD) P:NE. Pens of pigs (26 pigs/pen) were assigned to 6 dietary treatments in a randomized complete block design with 14 pens/treatment. Diets consisted of 2 levels of STTD P:NE: PIC recommendation (1.8, 1.62, 1.43, 1.25, 1.10, 0.99 g STTD P/Mcal NE from 11-22, 22-40, 40-58, 58-81, 81-104, 104-129 kg, respectively) or 75% of the PIC recommendation, and 3 analyzed Ca:P ratios: 0.90:1, 1.30:1, and 1.75:1. Diets were corn-soybean meal-based and contained phytase (Quantum Blue G, AB Vista, Marlborough, UK; 500 to 210 FTU/kg with release values from 0.13 to 0.07% STTD P). There was a Ca:P×STTD P:NE interaction (P &lt; 0.05) observed for ADG, G:F and final BW. For ADG and final BW, when feeding 75% of PIC STTD P recommendation, increasing analyzed Ca:P ratio decreased ADG and final BW (linear, P&lt; 0.001). But when feeding at PIC STTD P recommendation, increasing the analyzed Ca:P ratio tended to improve ADG and final BW (linear, P&lt; 0.10). For G:F, when feeding 75% of PIC STTD P recommendation, increasing analyzed Ca:P ratio tended to decrease G:F (linear, P &lt; 0.10), whereas in pigs fed diets that met PIC STTD P recommendations, increasing analyzed Ca:P ratio tended to improve G:F in a quadratic (P &lt; 0.10) manner. Pigs fed at PIC STTD P recommendations had increased ADG, final BW, and G:F compared with pigs fed 75% of PIC STTD P recommendations (P &lt; 0.001). In summary, pigs fed at PIC STTD P recommendations had improved overall ADG and G:F compared with pigs fed diets at 75% PIC STTD P recommendations. Additionally, increasing analyzed Ca:P ratio reduced ADG and G:F when STTD P was below PIC recommendations, but had marginal impacts when adequate STTD P was fed.

Abstract:
Abstract BACKGROUND AND IMPORTANCE: Meningiomas of the lateral ventricles are commonly located in the atria. Surgical access to such tumors is challenging because of their deep location and proximity to critical neurovascular structures, particularly if situated on the dominant side. Although a number of approaches have been described in the literature, most carry the risk of postoperative neuropsychological, visual, or speech deficits, especially when operating on the dominant hemisphere. The supracerebellar transtentorial transcollateral sulcus (STTCS) approach offers the potential to circumvent functionally important structures, reducing the risk of these approach-related neurological deficits. CLINICAL PRESENTATION: Two patients with dominant hemisphere trigonal meningiomas underwent surgical resection with the use of the STTCS approach. Neuronavigation was used to carefully plan the incision, craniotomy, and exposure, and also intraoperatively to orientate the operating surgeon at key steps, particularly when raising the tentorial flap in line with the tumor. Endoscopy was used to provide increased light intensity, an extended viewing angle, and higher magnification in comparison with a microscope. Specially designed tube-shaft instruments were also used to assist with manipulation through the narrow surgical corridor. In both cases, the tumors were fully resected without approach-related morbidity. CONCLUSION: The STTCS approach provides good access to tumors located in the trigonal region, reducing the risk of iatrogenic language or visual field deficits. In dominant hemisphere lesions, in the hands of an experienced neurosurgeon, the STTCS approach is an effective alternative to existing techniques.

Abstract:
Abstract Three hundred-fifty pigs (initially 11.9±0.56 kg) were used to evaluate effects of different bones and analytical methods on assessment of bone mineralization response to dietary P and vitamin D in nursery pigs. Pens of pigs (5 pigs/pen) were randomized to 6 dietary treatments in a randomized complete block design with 10 pens/treatment. After feeding diets for 28-d, 8 pigs/treatment were harvested for bone analysis. Treatments were: 1) P at 0.19% STTD P (deficient), 2) P at 0.33% STTD P (NRC requirement) using monocalcium phosphate, 3) P at 0.33% STTD P including phytase, 4) P at 0.44% STTD P (industry level) using monocalcium phosphate, phytase, no vitamin D, 5) diet 4 with vitamin D (1,653 IU/kg), 6) diet 5 with additional 2,000 IU/kg 25(OH)D3 (HyD). Final BW, ADG, and ADFI increased linearly (P &lt; 0.05) and G:F improved (quadratic, P &lt; 0.05) as P increased. The response to treatment for bone density and ash was dependent upon bone (density×bone interaction, P = 0.044; non-defatted bone ash×bone interaction, P = 0.060; defatted bone ash×bone interaction, P = 0.068). Pigs fed 0.19% STTD P had decreased (P &lt; 0.05) bone density and ash (non-defatted and defatted) for all bones compared with 0.44% STTD P, with 0.33% STTD P generally intermediate or similar to 0.44% STTD P. Pigs fed 0.44% STTD P with no vitamin D had greater (P &lt; 0.05) non-de-fatted fibula ash compared with all treatments other than 0.44% STTD P with added HyD. Pigs fed the 3 diets with 0.44% STTD P had greater (P &lt; 0.05) de-fatted 2nd rib ash compared with pigs fed 0.19% STTD P or 0.33% STTD P with no phytase. In summary, bone density and ash responses varied depending on bone. Differences in bone density and ash in response to vitamin D and P were most apparent with fibulas and 2nd ribs.

Abstract:
Abstract An experiment was conducted to test the hypothesis that formulating diets for pigs based on a ratio between standardized total tract digestible (STTD) Ca and STTD P instead of total Ca and STTD P increases the efficiency of Ca and P utilization. Forty barrows (59.4 ± 3.8 kg) were individually housed in metabolism crates and allotted to 4 corn-soybean meal diets and 2 periods of 11 d in a randomized complete block design. Diets were formulated using a 2 × 2 factorial design with 2 Ca requirement estimates (total Ca or STTD Ca) and 2 inclusion levels of microbial phytase (0 or 500 units/kg). Phytase was assumed to release 0.11% STTD P and 0.16% total Ca. Diets were formulated based on requirements for total Ca and STTD P and the ratio between STTD Ca and STTD P was 1.25:1 in diets formulated based on STTD Ca. Fecal and urine samples were collected from feed provided from d 6 to 9. Data for Ca and P balance were analyzed using a model that included the main effects of diet formulation and phytase level, the interaction between main effects, and the random effect of period. Interactions (P &lt; 0.05) between diet formulation and phytase level were observed for Ca intake, Ca in feces, Ca digestibility, Ca retained as a percentage of intake, P digestibility, P absorbed, and P in urine (Table 1). Despite being provided less (P &lt; 0.05) Ca, pigs fed diets formulated based on STTD Ca did not absorb or retain less Ca than pigs fed total Ca diets, but they absorbed more (P &lt; 0.05) P than pigs fed diets formulated based on total Ca. In conclusion, by formulating diets based on values for STTD Ca, P absorption was increased confirming detrimental effects of oversupplying Ca.

Research has examined various factors that may inhibit the career progress of females but, as far as the researcher has been able to ascertain, STTUC has not been sufficiently investigated as a factor that may hamper such progress. This study suggests such a focus because the work setting constantly places individuals in positions where they are obliged to present their abilities and/or achievements. In order to address the evident gap in existing research, this study investigated the STTUC framework within the organisational context in Botswana, Africa. The main aim of this study was to investigate the antecedents of STTUC and to explore gender differences in the STTUC experiences of black employees in Botswana. The antecedents explored included individual characteristics (specifically, collectivistic cultural orientation, traditional gender role orientation, affiliative needs, interpersonal sensitivity and competitiveness), family-work variables (specifically, instrumental support from the spouse/partner and family-work conflict), and organisational variables (focusing specifically on masculine values within the organisational culture).

Abstract:
This thesis addresses handoff issues in a WCDMA system with space-time block coded transmit antenna diversity. Soft handoff has traditionally been used in CDMA systems because of its ability to provide an improved link performance due to the inherent macro diversity. Next generation systems will incorporate transmit diversity schemes employing several transmit antennas at the base station. These schemes have been shown to improve downlink transmission performance especially capacity and quality. This research investigates the possibility that the diversity obtained through soft handoff can be compensated for by the diversity obtained in a transmit diversity system with hard handoff. We analyze the system for two performance measures, namely, the probability of bit error and the outage probability, in order to determine whether the improvement in link performance, as a result of transmit diversity in a system with hard handoffs obviates the need for soft handoffs.

Abstract:
Dans cette thèse, les récepteurs de Wiener optimaux et sous-optimaux à rang réduit pour le CDMA sont étudiés. La thèse est divisée en deux partie. Dans la première partie, les récepteurs sous-optimaux consisant d'un égaliseur de Wiener à rang réduit au rythme chip suivi de desétalement sont étudiés. Un égaliseur à rang réduit est un égaliseur pour lequel quelques coefficients seulement sont optimisés. Le rang du filtre est le nombre de coefficient optimisés. Dans la deuxième partie, la performance asymptotique de quelques récepteurs linéaires est evaluée. Pour étudier la performance asymptotique, on suppose que les codes d'étalement sont aléatoires suivant une certaine distribution. Le rapport Signal à Interference plus Bruit (SINR) à la sortie du récepteur peut ainsi être interprété comme une variable aléatoire. Il est possible de démontrer que ces variables aléatoires tendent vers des valeurs deterministes finies quand le facteur d'étalement et le nombre d'utilisateurs tendent vers l'infini de telle façon que leur rapport reste fini. Ces limites peuvent être utilisées pour comprendre les facteurs qui controlent la performance tels que le canal de propagation, le bruit et le facteur de charge. On présente les résultats précédents relatifs au récepteurs de Wiener optimaux à rang réduit. Ces résultats sont après étendus au récepteurs de Wiener sous-optimaux à rang réduit.On démontre que la convergence du SINR d'un récepteur de Wiener à rang réduit vers celui du récepteur à rang plein est très rapide. Dans le dernier chapitre, on étudie la performance asymptotique de la diversité à la transmission combinée avec un récepteur RAKE où un égaliseur MMSE.

Abstract:
Dans la recherche de modulations adaptées à la voie descendante des réseaux cellulaires 4G, i.e. permettant le transfert de données à haut débit tout en garantissant une grande mobilité aux utilisateurs, les systèmes MC-CDMA s'affirment aujourd'hui comme des solutions à fort potentiel. Ces techniques reposent sur la combinaison des modulations à porteuses multiples et l'étalement de spectre qui permet l'accès multiple par répartition de code. En parallèle, les sytèmes MIMO constituent une nouvelle voie très prometteuse améliorant notablement l'efficacité spectrale des systèmes hertziens via la dimension spatiale. Cette thèse porte sur l'optimisation des systèmes MIMO/MC-CDMA par l'étude des codes temps-espace en blocs (STBC)ou en treillis (STTC).

Après un état de l'art relativement exhaustif des systèmes MIMO en général et des codes temps-espace en particulier, nous proposons de nouveaux codes STBC orthogonaux, puis une représentation polynômiale permettant la comparaison des codes STTC existants. La combinaison STBC/MC-CDMA étudiée ensuite améliore sensiblement les performances d'un système MC-CDMA SISO tout en autorisant un décodage relativement simple. Leur optimisation repose sur des techniques de détection mono-utilisateurs ou multi-utilisateurs. Leur performances sont évaluées dans des configurations MISO ou MIMO, aussi bien sur des canaux théoriques que sur des canaux réalistes. Enfin, la combinaison STTC/MC-CDMA est étudiée.

Dans ce mémoire nous étudions des techniques de réception multi-antennes capables de supprimer au mieux les interférences. Tout d'abord, nous avons généralisé le concept des codes SOSTTC, au cas de systèmes de transmission à trois antennes en utilisant des algorithmes de partitionnement des constellations transmises. Nous avons alors obtenu des codes spatio-temporels en treillis qui utilisent des codes spatio-temporels comme composants de base et qui présentent des gains de codage supérieurs aux STTC de la littérature. Nous avons ensuite étudié la concaténation parallèle et série de tels codes pour obtenir des turbo récepteurs. Nous finissons par l'étude des systèmes en couches. Nous étudions la structure d'un turbo-annuleur d'interférences concaténé avec des codes de type LDPC,. Puis nous généralisons l'utilisation des codes STTC qui utilisent des STBC comme composants de base au contexte des systèmes en couches pour un nombre d'antennes d'émission multiple de trois
This work, propose some system architectures which are able to suppress as better as possible the MIMO system interferences. First we have generalized SOSTTC concept, for three transmit antenna case, by using set partitioning. We propose a new STBC design for the case of three transmit antennas. Our goal is to show that it is possible to build powerful STTC codes with STBC designs with maximum transmission rate, even in the case where orthogonality is broken. Then, we studied serial and parallel concatenation to obtain turbo receivers. We found that if we use our new code in a serial concatenation with the Vucetic's turbo STTC, we are able to obtain outstanding performances. At the end, we present two new architectures of layered space-time codes. First we show a combination of BLAST architecture and of special STTC codes which are developed in the previous part, and second, we combine irregular LDPC codes with BLAST architecture

Abstract:
The spectrum used by Code Division Multiple Access (CDMA) allows for a signal with a greater bandwidth by spreading electromagnetic energy. Multi-Carrier CDMA (MC-CDMA) is a telecommunications numerousentrée strategy that spreads each user symbol across the frequency domain with distinct codes. Cognitive Radio (CR) is a vibrant spectrum admittance enabling technology by dynamically allocating space for fundamental users by modifying its settings and base station. Two models for people on the cognitive spectrum are Opportunistic Spectrum Access (OSA) and Concurrent Spectrum Access (CSA). Using Co-Channel Interference (CCI) and Adjacent Channel Interference (ACI), the MC-CDMA system is an effective accessing strategy for multi-user data transmission (ACI). Multiple-Input Multiple-Output (MIMO) involving Space-Time Transmit Diversity (STTD), Spatial Multiplexing (SM), and collaborative MIMO is used for numerous data communication, and dependable Bit Error Rate (BER) presentation is attained. STBC (Space Time Block Coding) is equipped with two antennas and codes for data transmission across multiple antennas. At the receiver, STBC offers channel state information while maintaining a low level of complexity. The image’s pixels will be shuffled using Arnold’s Cat Map (ACM) encryption method. When compared to other compression methods, Integer Wavelet Transform (IWT) compression is stress-free. The Internet of Things (IoT) is used to examine tracklatency and power stages, STTD MC-CDMA faultoutput utilizing cognitive spectrum, and channel simulated parameterization. The output on fault levels with patient caring using Stanford University Interim (SUI) and Long Term Evolution (LTE) techniques with a Double STTD (DSTTD) assisted MC-CDMA cognitive spectrum system.

Abstract:
Deep Learning architectures for time series require a large number of training samples, however traditional sample size estimation for sufficient model performance is not applicable for machine learning, especially in the field of electrocardiograms (ECGs). This paper outlines a sample size estimation strategy for binary classification problems on ECGs using different deep learning architectures and the large publicly available PTB-XL dataset, which includes 21801 ECG samples. This work evaluates binary classification tasks for Myocardial Infarction (MI), Conduction Disturbance (CD), ST/T Change (STTC), and Sex. All estimations are benchmarked across different architectures, including XResNet, Inception-, XceptionTime and a fully convolutional network (FCN). The results indicate trends for required sample sizes for given tasks and architectures, which can be used as orientation for future ECG studies or feasibility aspects.

Abstract:
Drone adalah pesawat tanpa awak yang dikendalikan dari jarak jauh. Pesawat tanpa awak atau Pesawat nirawak (Unmanned Aerial Vehicle atau UAV), adalah sebuah mesin terbang yang berfungsi dengan kendali jarak jauh oleh pilot atau mampu mengendalikan dirinya sendiri, menggunakan hukum aerodinamika untuk mengangkat dirinya, bisa digunakan kembali dan mampu membawa muatan baik senjata maupun muatan lainnya. Perkembangan teknologi membuat drone juga mulai banyak diterapkan untuk kebutuhan sipil, terutama di bidang bisnis, industri dan logistik. Dunia industri bisnis, drone telah diterapkan dalam berbagai layanan seperti pengawasan Infrastruktur, pengiriman paket barang, pemadam kebakaran hutan, eksplorasi bahan tambang, pemetaan daerah pertanian, dan pemetaan daerah industri. Berdasarkan jenisnya, terdapat dua jenis drone, yaitu multicopter dan fixed wing. Fixed wing memiliki bentuk seperti pesawat terbang biasa yang dilengkapi sistem sayap. Tipe fixed-wing memerlukan desain aerodinamika pada sayap dan badannya sehingga perancangannya cukup rumit. Multicopter yaitu jenis drone yang memanfaatkan putaran baling-baling untuk terbang. Drone Sekolah Tinggi Teknologi Kedirgantaraan (STTKD) memiliki jenis multicopter, dan sudah dipergunakan untuk pemetaan di wilayah Kulonprogo terletak di Desa Glagah Temon dekat runway calon bandara dengan waktu operasional Drone STTKD kurang lebih 20 menit dan beban yang dapat diangkat 1 kg.
