Load modelling is the first and most essential step in achieving all the above said tasks. Even though many appliance modelling schemes are presented in the literature, no considerably influential work has been done on modelling appliances under voltage fluctuating environment. Motivated by this fact, we present the design and analysis of a Volterra based appliance modelling scheme which can be used in a voltage fluctuating environment. Principles of Volterra filter, least mean square algorithm for Volterra filter coefficient approximation and applicability of Volterra filter for appliance modelling are discussed. Further, a case study is presented to validate and identify the performance of the model using a data set obtained from a real household. Obtained results show that, Volterra filter can be utilized as an efficient tool for appliance modelling in a supply voltage fluctuating environment. Finally, how Volterra filter modelling can be extended to achieve the non intrusive load monitoring task is discussed.","PeriodicalId":404432,"journal":{"name":"2018 IEEE Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124067943","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}

Voice controlled wheelchairs give its user a chance to interact with the wheelchair in a humane manne. Due to the uncertaities of the voice commands and unreliability of using one interaction modality, user safety is compromised. In natural wheelchair user and caretaker conversation a lot of distance related uncertain instructions like ‘little’ and ‘far’ will be used. With incorporating these uncertain terms, the interpretation of voice commands will be enhanced. In most existing systems, Joystick support is used as backup modality. Even though this is intended as a safety feature, accidental joystick operation can lead to unfortunate situations. Therfore a reliable safety system considering multimodal aspect of two modalities is needed. Therefore this paper proposes a voice controlled intelligent wheelchair system incorporating uncertain voice information with safe navigation system using multmodal approach. Uncertain Information Module(UIM) have been introduced in order to interpret uncertain voice information and Multimodal Safety System is introduced in order to ensure user safety. Usability experiments have been carried out to evaluate the reliability of voice control system and Multimodal safety system.","PeriodicalId":404432,"journal":{"name":"2018 IEEE Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132029561","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 multispectral image is rich in information compared to a normal RGB image. Therefore, a multispectral image can be used to classify samples more accurately than an RGB image. This paper discusses a design of a multispectral imaging system that can be used to assess the quality of meat. The system is comprised of six LEDs with nominal wavelengths between 405 nm and 740 nm. The light emitted from LEDs reach the meat sample placed inside a dark chamber through an integrating hemisphere. LEDs are lighted one at a time and images of the meat sample are captured for each flash separately using a smartphone camera. Eventually, all the images of the meat sample, taken at a specific time instance were integrated to form the multispectral image. The meat samples stored at $4 circ mathrm {c}$ were imaged up to four days at predetermined time intervals using the designed system. Once the data acquisition was completed, all the pixels of the multispectral image were represented as points in high dimensional space, which was then reduced to a lower dimensional space using Principal Component Analysis (PCA). It was observed that images of meat sample obtained at different time instances clustered into different regions in the lower dimensional space. The experiment was performed with chicken meat samples. This proves the viability of using multispectral imaging as a non-invasive and non-destructive method of assessing meat quality according to certain quality parameters. Off-the-shelf electronic components and a regular smartphone were used to build the system, thus making the system cost-effective.","PeriodicalId":404432,"journal":{"name":"2018 IEEE Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128416919","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}
