During the switching transients, the turn-on and turn-off delay time, current/voltage overshoot, switching losses dissipated in IGBT and electromagnetic interference are all related to its driving circuit. Hence, an advanced and appropriate driving strategy can further improve the performance and reliability of the power electronics systems, and exerts the full potential of the power semiconductor device. A comparative study of typical active gate drive methods has been conducted and switch dynamics and stress factors are evaluated by analytical expressions and simulations. Their pros and cons have been discussed.","PeriodicalId":214121,"journal":{"name":"2016 International Conference for Students on Applied Engineering (ICSAE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134111384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing methods are not sensitive enough for detecting minor deviations from healthy gaits. That is important because these minor deviations could develop into a severe painful lameness condition. We introduce a dynamic novel proxy for early stage lameness by analyzing the height movements from an overhead-view 3D video data. These movements are derived from key regions (e.g. spine, hook joints, and sacroiliac joint). The features to these key regions are automatically tracked using shape index and curvedness threshold from the 3D map. Our system is fully automated, covert and non-intrusive. This directly affects the accuracy of the analysis as we are able to observe the animals without spooking them. We believe that our proposed method could be used on other animals, i.e. predator quadrupeds where human presence is difficult.","PeriodicalId":214121,"journal":{"name":"2016 International Conference for Students on Applied Engineering (ICSAE)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114432245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These characteristics has seen CAP being implemented as an alternative to the well-known discrete multitone (DMT). However, the sensitivity of CAP to timing jitter is high due to its use of pulse shaping which eliminate the need for carrier modulation and carrier frequency recovery in its tranceiver architecture. In this paper, the impact of timing jitter on the performance of CAP technique is investigated. It is shown that with increasing timing jitter, the bit error rate (BER) performance of CAP-4 degrades and reaches an error floor when the timing jitter (τ) reaches 20% of the symbol duration, T. Although the timing jitter effect is observed to reduce with increasing roll-off factor, α, the resulting performance degradation increases with the data constellation size. With a 0.02T timing jitter, CAP with 64 data constellation points (CAP-64) and 0.15 roll-off factor reaches an error floor at a BER of 2 × 101. The results of this paper show that although CAP offer implementation simplicity, timing synchronization is a critical requirement in its receiver design.","PeriodicalId":214121,"journal":{"name":"2016 International Conference for Students on Applied Engineering (ICSAE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A good example of an application where this is happening is street lighting. The increasing use of LEDs is due to their advantages compared to other sources of illumination. However, LEDs are not without disadvantages. One of their main drawbacks when used for street lighting without an adequate secondary optic is that they tend to produce a circular footprint with high intensity at the centre and low intensity at the edge of the illuminated area, which prevents them from satisfying national and international standards for uniformity of illumination. This paper presents a new energy mapping method to design a freeform lens to generate uniform illumination of over 95% on the target plane. The lenses presented in this paper have been designed with two different entrance apertures: (i) A hemisphere subtracted aperture (ii) a flat entrance aperture.","PeriodicalId":214121,"journal":{"name":"2016 International Conference for Students on Applied Engineering (ICSAE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129278184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel intelligent intrusion detection is proposed to secure the external communication system of self-driving and semi-self-driving vehicles. This system is based on the Integrated Circuit Metric technology, which has the ability to protect systems using features of the system itself. The detection system, called the ICMetric-IDS, is based on novel and unique features, which have been generated from bias values of magnetometer sensors as well as features which have been extracted from a trace file of simulated vehicle network traffic. Practical implementation and testing of the system demonstrate the efficiency in the detection of malicious behaviour.","PeriodicalId":214121,"journal":{"name":"2016 International Conference for Students on Applied Engineering (ICSAE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126393855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed network includes a set of in situ wireless nodes each connected to a production line and a data sink located in a control room for data collection, data visualization and user interaction. The features of this system include the ability to real time monitor energy consumption, low cost and cable-free deployment of multiple monitor nodes to cause no additional hazards in the production environment.

High speed measurement facilitates testing various load scenarios and manufacture throughput; high measurement accuracy and resolution is required for drawing the correct conclusions on the efficiency of design alterations. Ultrasonic temperature sensors can quickly sense temperature with high resolution and accuracy across the entire ultrasonic pathway. However, conventional high resolution ultrasonic sensors are expensive. By contrast, oscillating ultrasonic temperature sensors can be implemented using mass produced transducers and electronic parts at a fraction of the price of conventional high resolution ultrasonic measurement equipment.
