Повний текст джерелаSHOP 360 ° is a virtual store and application for mobile devices that will help Peruvian families in making domestic purchases for their homes in a virtual way, without the need to leave home, close to the place of their residence or closest environment. At the same time, it will provide support to convenience stores that wish to promote their brand online in order to generate higher sales. This application has instant location, which allows you to view the establishments closest to you. In addition, it allows you to see the variety, stock and prices of different convenience stores. Payments can be made in different ways. For example: bank transfers, yape, lukita, debit or credit cards. This project arose from the necessity of the costumers and the convenience store owner due to the COVID 19 pandemic that we are experiencing in the current year 2020. In many cases, the population stopped going to the convenience stores, supermarkets, and local markets because the fear of catch the virus from another person. That is why technology began to be used more, such as virtual purchases and deliveries. The convenience stores associated with SHOP 360° are clear about the service they provide to the user meanwhile they are respecting security protocols. Currently, there is no direct competition that focuses on entrepreneurs. For this reason, Shop 360 ° was born to provide support to the small entrepreneur. Likewise, we have a competitive and motivated team to carry out this project, with the personalized attention of costumers.

Ship's lines are designed such that they are fair. To the naval architect, fairness means that the lines exhibit a continuous second derivative. This is the definition of a spline. Before the advent of digital computers, naval architects checked every line on a lines plan for fairness by bending a thin stick of wood, called a batten, on the line. If the line followed the natural bend of the batten, the line was fair. This phenomenon follows from the beam equation, which shows that the minimum energy in the beam occurs when the beam has a continuous second derivative of position. Hydrostatics lies at the heart of naval architecture. The hydrostatic properties of a hull are determined by the lines and their interpretation using rules of integration. The resulting analysis is presented in the form of graphs, termed the "curves of form" or "displacement and other curves." An intact stability analysis follows naturally from the hydrostatic analysis. Hydrostatics (determination of KM) coupled with a KG value can be used to predict initial stability. This intact stability analysis evaluates the range of stability at both small and large angles of inclination. The responses of the hull to static and dynamic loading situations can be inferred from the curves of form. Their most basic use is to determine the static waterline in various loading scenarios. A more subtle use is to determine the correct placement of the vertical center of gravity to ensure a sea kindly roll period, stability in beam winds, and stability in high speed turns. Various computational tools can be used to compute the hydrostatic and stability properties of a ship. This thesis explores the results from two computer aided design tools used by the U.S. Navy and commercial industry; Advanced Surface Ship and Submarine Evaluation Tool (ASSET) and Program for Operational Ship Salvage Engineering (POSSE).

The traditional Economic Order Quantity (EOQ) model ignores the physical limitations of distribution practices. Very often distribution centers (DC) have to deliver merchandise in manufacturer-specified packages, which can impose restrictions on the application of the economic order quantity. These manufacturer-specified packages, or ship-packs, include cases (e.g., cartons containing 24 or 48 units), inners (packages of 6 or 8 units) and eaches (individual units). For each Stock Keeping Unit (SKU), a retailer decides which of these ship-pack options to use when replenishing its retail stores. Working with a major US retailer, we have developed a cost model to help determine the optimum warehouse ship-pack. Besides recommending the most economical ship-pack, the model is also capable of identifying candidates for warehouse dual-slotting, i.e., two picking modules for the same SKU that carry two different pack sizes. We find that SKUs whose sales volumes vary greatly over time will benefit more from dual-slotting. Finally, we extend our model to investigate the ideal case configuration for a particular SKU, that is, the ideal size for an inner package.

With the U.S. Navy's continued focus on Integrated Fight Thru Power (IFTP) there has been an ever increasing effort to ensure an electrical distribution system that maintains maximum capabilities in the event of system faults. Non-Intrusive Load Monitoring (NILM), which has been used extensively for condition based maintenance applications, could simultaneously be used to enhance the existing zonal protection system employed with Multi-Function Monitors (MFM). A test platform with three 5000 watt synchronous generators is being constructed to emulate a U.S. Navy DDG 51 FLT IIA class ship electric plant. This is being accomplished in order to evaluate the feasibility of improving the fault isolation capabilities of the MFM with NILM implementation. The first step in this endeavor will be to electrically relate the test platform to the DDG electric plant. In order to accomplish this step, the fault simulation results from the test platform will be compared to simulated faults using U.S. Navy data from DDG 51 electric plants. This will allow for the fault isolation results from the test platform to be related to the DDG 51electric plant.

With the U.S. Navy's continued focus on Integrated Fight Thru Power (IFTP) there has been an ever increasing effort to ensure an electrical distribution system that maintains maximum capabilities in the event of system faults. This is to ensure that the crew has the ability to complete real time tactical missions in the event of battle damage to any localized portions of the electrical distribution system. Fault isolation is a priority component of the U.S. Navy's Next Generation Integrated Power System (NGIPS) Roadmap, which lays out the framework as well as milestone dates for future development. Non-Intrusive Load Monitoring (NILM), which has been used extensively for condition based maintenance applications, could simultaneously be used to enhance the existing zonal protection system employed with Multi-Function Monitors (MFM). NILM may be able to, inexpensively, use the existing current and voltage sensors available from the MFM hardware to determine electrical loading which could allow for faster fault isolation capability. A test platform with three 5000 watt synchronous generators is being constructed to emulate a U.S. Navy DDG 51 FLT IIA class ship electric plant. This is being accomplished in order to evaluate the feasibility of improving the fault isolation capabilities of the MFM with NILM implementation.

Diesel and gas turbine electric ship propulsion are of current interest for several types of vessels that are important for commercial shipping and for the next generation of war ships. During the design process of a platform, a choice has to be made between two different fundamental concepts regarding propulsion; a conventional arrangement, and a diesel or gas turbine electric propulsion. For both concepts, the electrical installation is present and the demand for additional electric energy becomes a dominant parameter. In both cases, the selection of the prime mover significantly influences the effectiveness of the design. In this thesis, the simulation modeling of a complete propulsion system will be attempted, with overall emphasis on the prime movers. In the first part a diesel engine is considered. The time delay between changing a set point for the revolutions of the engine and the change of the real revolutions is often modeled as a first order system. However, this modeling is too simple to describe the real behavior of the diesel engine. More complex models exist, but in general they are too complex, describing the full thermodynamic behavior of diesels.
(cont.) So there is a need for a model that is more advanced than a first order system and less complex than complete thermodynamic models. Such a model has been derived, based on the Seiliger (thermodynamic) process. The results of the model show that the diesel engine behaves like a second order system when operating in the governor area and more like a first order system in the constant torque (overload) area. The simulation model of a diesel engine can be regarded as an explanation of the real engine operation, which combines the mathematical relationship between the relative components and can be used to simulate dynamic loading of the diesel engine. In the second part, a development of a nonlinear gas turbine model for loop- shaping control purposes is presented. The nonlinear dynamic equations of the gas turbine are based on first engineering principles. In order to complete the model, constitutive algebraic equations are also needed. These equations describe the static behavior of the gas turbine at various operating points.
(cont.) The complete, substituted nonlinear model is presented along with its model verification results based on a simulator and measured data. A mathematical description for the electric part of the propulsion and energy generation system with respect to numbers of components such as generators and thruster drives is attempted. Other electrical loads may be represented with an aggregate load. Based on the control functions focus on power production, advanced dynamic models shall be used for the generators and simplified static models shall be used for thruster drives and other loads. The final model shall be in a state-space vector form, suitable for control design. As a conclusion, a reliability analysis on the decision for the electric propulsion system is utilized based on market data, speed and electric energy requirements studies. The purpose of this study is to justify the employment of innovative and efficient electric propulsion systems for the future needs of the commercial and naval ship industries.

Повний текст джерелаA critical factor in the success of an amphibious operation is how well the load plan supports the landing plan. The current manual system for ship load planning is time consuming and subject to error. A computer system currently under development by a contractor will decrease planning time and reduce mistakes by automating many details of the planning process. A method to assess the quality of load plans and make comparisons among them is also essential to improved planning. The scoring algorithm developed in this paper implements a measure of effectiveness (MOE) to make these comparisons by scoring a load plan's ability to support the landing plan. The algorithm provides the ability to differentiate qualitatively among loads by computing penalty scores for the critical areas of equipment left behind, compartment location, and compartment access.

Повний текст джерелаThis survey is about how to measure the sea state. A view of the existing tecniques on the market and, when possible, the prices of now existing products is presented. The mainpurpose is to investigate the possibility to measure waves with an inexpensive free drifting wavebuoy. The maximum material cost has been set to around 3000 kr, which severely limits the possibilitis. Ideas of how to analyse data from such a buoy and analysehow reliable this data can possibly become, is presented. A prototype of a wavebuoy is described and also the test results of the buoy, together whith descriptions of how thetests have been conducted. Effort has been made to put light on the kind of problems and errors that may occure when using these methods. The tests have shown that it is possibleto measure waves with a free floating wavebuoy with only one accelerometer as activesensor. The design of the buoy is important to minimize the movements of the buoy,since when tilted the buoy does not give accurate data. The incoming data must befiltered and when that is done the bandwhith of the buoy decreases. In this case the buoycan measure waves with frequencies over 0.14 Hz, which in deep water means waves with wavelength less than 80 m. It is important to know that far too few tests in different wavespectras have been conducted to be sure of the achieved results. Further tests and investigations should be made and this survey is to be seen as a first step.

Повний текст джерелаCurrent fiscal constraints are driving the reduction of system life cycle cost (LCC). A key objective of HSI is the reduction of operational cost and the improvement of operational performance. This thesis seeks to develop a Human Systems Integration (HSI) Synthesis Model for Ship Design. This model is based on the premise that ship design characteristics interact with the domains of HSI. The thesis begins with an historical overview of ship architecture and technology and their interactions with the domains of HSI. The HSI Synthesis Model for Ship Design was developed using the Framework of Naval Postgraduate Schools Systems Engineering Ship Synthesis Model. Quantitative data analysis was conducted using Offshore Patrol Vessel (OPV) design data from Information Handling Services (IHS) Janes database. The data analyzed included 35 ships from 21 nations. Multiple regression analysis consisted of nine independent ship design variables and a response variable of manpower. Data analysis revealed that ship length and ship draught were statistically significant. The proposed HSI Synthesis Model accounted for 49 per cent of the variance of crew complement. This thesis lays the foundation for future qualitative and quantitative analysis of the interaction between ship design characteristics and HSI domains. Additionally, it provides an initial HSI model that can be expanded upon by including additional HSI domains and, ultimately, may lead to a viable design tool for HSI practitioners and systems engineers.

This thesis develops a new decision making framework for initial cruise ship design. Through review of effectiveness analysis and multi-criteria decision making, a uniform philosophy is created to articulate a framework that would enable a designer to more accurately assess what design alternatives are more important than others and how their changes affect the overall system being designed. Through a brief historical account, top-level Measures of Merit are developed and used with the framework and then applied to a requirements and effectiveness case study on initial concept development of a cruise ship. This is performed using Response Surface Methods to enable the user to visualize the design space as well as interact with it; the results and methods to visualize the design space are discussed. Finally, a Unified Tradeoff Environment is discussed, a framework that pools the aforementioned requirements and effectiveness analysis with design and technology forecasting to enable the user to make better informed requirements derivation and design selection.

This study considered how appropriate different market-based approaches are for the reduction of ship air emissions, particularly CO2. Furthermore, the study also considered which types of market-based tools may be available for application to the shipping industry. This project was not intended to design or optimize a system for the maritime community. The study considered the current input and discussions within the International Maritime Organization and its Marine Environment Protection Committee and identified three major thought patterns in proposed systems for the maritime industry: (1) an emissions trading scheme for the shipping industry, (2) CO2 indexing, and (3) alternative approaches. The most significant alternative approach is to place a levy on fuel bunkers. Other alternative approaches could involve hybrid systems using any combination of the other systems mentioned. The study identified a number of unresolved issues and tradeoffs that could hinder the implementation of these systems. These industry-specific issues include technical, policy, administrative, and infrastructure considerations. Currently, there is no consensus on which type of system to use or even whether any of these systems will be used. The study concludes with recommended steps towards emissions management for ship owners and operators.

Повний текст джерелаGenom att inkludera matematiska modeller som beskriver ett systems dynamik i styrningsalgoritmer, kan man åstadkomma en automatisk styrning med förbättrad effektivitet, robusthet och noggrannhet. Med dessa modeller går det att förutsäga beteendet hos systemet och därmed öppnas också möjligheten att använda sig av detta i styrningen. Problemet är att om dessa modeller inte beskriver systemets dynamik tillräckligt bra kan prestandan istället sänkas genom dessa metoder. Den här sortens problem kan man lösa genom att aktivt skatta systemets dynamik under körning, med hjälp av metoder för systemidentifiering, signalbehandling och sensorfusion. I denna exjobbsrapport har möjligheterna att skatta ett skepps girdynamik undersökts. Den matematiska modell som beskriver skeppets dynamik är en grålådemodell som baserar sig på fysikaliska och mekaniska samband. Denna modells egenskaper beskrivs därför av fysikaliska storheter så som massa, tröghetsmoment och tyngdpunkt, vilka alla är okända. Detta innebär att vid modellskattning skattas dessa fysikaliska storheter, vilka kan vara av stort intresse. En simuleringsmiljö med en skeppsmodell med fyra frihetsgrader har skapats och använts för att validera metoder för systemidentifiering. En modell av ett roterbart framdrivningssystem har också härletts och inkluderats i simuleringsmodellen. Vid systemidentifiering och skattning av skeppets egenskaper har dels inverkan av mätbrus analyserats samt även möjligheter till att detektera skillnader i dynamik. Detta har gjorts med Monte Carlo-simuleringar av skattningsmetoden med olika brusrealiseringar för att analysera hur mätbrus påverkar variansen och metodfelet hos skattningarna. Resultaten visar att vissa parametrar skattas med större noggrannhet och hos dessa kan därmed en förändring i dynamik identifieras när endast tio minuter av data har använts. En metod baserad på kumulativ summering av residualer har formulerats och validerats, detta för att undersöka om en sådan metod kan ge snabb och effektiv detektion av systemförändringar. Resultat visar på robusthet i att detektera skillnader i dynamik efter ungefär fyra minuter av datainsamling. Slutligen har metoderna validerats på data insamlad på ett riktigt skepp för att undersöka potentialen under verkliga omständigheter. Resultaten visar att just denna data inte är lämplig för denna applikation samt några problem som kan leda till försämrade resultat.

This thesis describes an adaptable component level machinery system weight and size estimation tool used in the context of a preliminary ship system design and naval ship concept design. The system design decomposes the system of systems into three intersecting areas: physical, logical, and operational to describe the spatial and functional relationships of the system together with their time dependent behavior characteristics. Following an Architecture Flow Optimization (AFO), or energy flow analysis based on this system design, vital components are sized based on their energy flow requirements for application in the ship synthesis model (SSM). Previously, components were sized manually or with estimated equations. This was not workable for assessing many designs in concept exploration and outdated equation models based on historical data were not sufficiently applicable to new ship designs. The new methodology presented in this thesis uses the energy flow analysis, baseline component data, and physical limitations to individually calculate sizes and weights for each vital component in a ship power and energy system. The methodology allows for new technologies to be quickly and accurately implemented to assess their overall impact on the design. The optimized flow analysis combined with the component level data creates a more accurate design that can be analyzed to assess the impact of various systems and operational cases on the overall design. This thesis describes the SSM, discusses the AFO’s contribution, and provides background on the component sizing methodology including the underlying theory, baseline data, energy conversion, and physical assumptions.
