Studies on Stability and Stabilization of Randomly Switched Systems

This thesis presents a study on stability analysis and stabilizing controller synthesis of randomly switched systems. These systems have two ingredients: a family of nonlinear subsystems and a random switching signal that specifies which subsystem is active at each time instant. In broad strokes, the approach pursued here consists of identifying key properties of the switching signal and the family of subsystems, and finding conditions to connect these two sets of properties such that the switched system has some desirable stability characteristics. The method of multiple Lyapunov functions is employed in conjunction with some statistical properties of the switching signal for the analysis. The results apply to situations where traditional methods involving infinitesimal generators are difficult to apply, either due to insufficient information about the properties of the switching signal, or due to nontrivial dependence on its past history. Some of the results have conceptual parallels in deterministic switched systems theory. Stability in the presence of exogenous deterministic inputs is also considered, properties analogous to input-to-state stability are proposed, and sufficient conditions are established under which a randomly switched system exhibits these properties. Stabilizing controllers are synthesized for randomly switched systems with control inputs; the analysis results are utilized in conjunction with multiple control-Lyapunov functions and universal formulas for feedback stabilization of nonlinear systems. This approach lends a modular structure to the synthesis stage and facilitates the usage of standard off-theshelf controllers.

Lessons Learned from a High School Robotics Workshop

Statistics data show that there is a huge gender gap in science, technology, engineering, and math (STEM) workforces in the United States. In order to encourage more women to work in the STEM fields, the first step is to attract women to pursue the STEM majors. Robotics provides an easy, fun, and exciting environment for young minds, while exposing them to technologies at the same time. This paper describes our collaboration with an all-girl high school in offering their students a year-long robotics workshop. The motivation of this collaboration is two-folded. On one side, the school administration is interested in bringing engineering and technologies to their curriculum, which is currently missing. From our side, we would like to motivate and recruit more female students to the STEM fields by showing them the emerging and multidisciplinary aspects. Our collaboration with the local high school started in Fall 2014 by offering their students a yearlong robotics workshop. Our objective is to utilize the robotics workshop to introduce STEM concepts to high school students, and encourage them to be interested in an engineering and science career. A sequence of workshop topics were given to introduce the fundamentals of robotics science and the basic components of a robotics system, including hardware, software, programming, sensors, and control. The students would gain intensive experience working with the robots. In addition to introducing the fundamentals, we planned to prepare the students with the necessary knowledge and skills to participate in national robotics competitions, such as FIRST® Tech Challenge (FTC) and FIRST® Robotics Competition (FRC). At the time of writing, the robotics workshop has been offered for one year and a half. Workshop lessons were offered bi-weekly. At the end of year 2014, a survey was conducted to collect feedbacks from the students. At the end of Spring 2015, we also had direct conversation and discussion with the teachers in the high school to gather their opinions. Continuous and constant modifications and adjustment were performed to give the students an easy yet fruitful learning experience. This paper presents our curriculum development, implementation and modifications of the lesson plan, feedbacks from students and their high school teachers, and the lessons we learned from offering this workshop.
A human factors perspective on automated driving

ABSTRACT Automated driving can fundamentally change road transportation and improve quality of life. However, at present, the role of humans in automated vehicles (AVs) is not clearly established. Interviews were conducted in April and May 2015 with 12 expert researchers in the field of human factors (HFs) of automated driving to identify commonalities and distinctive perspectives regarding HF challenges in the development of AVs. The experts indicated that an AV up to SAE Level 4 should inform its driver about the AV's capabilities and operational status, and ensure safety while changing between automated and manual modes. HF research should particularly address interactions between AVs, human drivers and vulnerable road users. Additionally, driver-training programmes may have to be modified to ensure that humans are capable of using AVs. Finally, a reflection on the interviews is provided, showing discordance between the interviewees’ statements – which appear to be in line with a long history of HFs research – and the rapid development of automation technology. We expect our perspective to be instrumental for stakeholders involved in AV development and instructive to other parties.
Adopting agile software development practices: success factors, changes required, and challenges

Agile software development is an emerging approach in software engineering, initially proposed and promoted by a group of seventeen software professionals who practice a set of "lightweight" methods, and share a common set of values of software development. They consolidated their thoughts, and defined these methods as "agile". The approaches are based on experiences, and best practices from the past by the above-mentioned group of seventeen software professionals. As an emerging approach of this century, agile software development has undergone limited number of empirical studies. In this Thesis, we advance the state-of-the-art of the research in this area by conducting survey-based ex-post-facto empirical (quantitative) studies by identifying the success factors from the perspective of software practitioners in agile software development projects, determining the key changes traditional projects have to undergo to adopt agile practices in their projects, and the challenges/risks they have to undergo for transition. We describe theoretical frameworks we have developed to address our research questions, the hypotheses we have conjectured, the research methodology, the data analysis techniques we have used, and the results we have obtained from the data analysis. The study was conducted using a survey-based methodology consisting of respondents who practice agile software development methodologies and who have experience practicing plan-driven software development in the past. The study indicates that nine of the fourteen hypothesized factors have statistically significant relationship with success. It also suggests a ranked list of changes required and challenges involved in adopting agile software development methodologies by projects practicing plan-driven software development.
Mitigation of current harmonics for multi-pulse diode front end rectifier systems

18 pulse rectifier systems have been shown to be a cost effective harmonic solution in many industries where IEEE 519 is specified. However, multi-pulse rectifiers are susceptible to phase unbalance of the source voltage and preexisting harmonic voltages. A small amount of voltage unbalance can cause a large amount of current harmonic injected back to the input source. Consequently, a stricter preexisting voltage THD condition has to be specified for an 18 pulse rectifier to meet the IEEE 519 current harmonics requirement. This paper introduces a DC link passive filtering method to solve this problem. This method greatly reduces the current harmonics caused by the phase unbalance, the 5/sup th/, and the 7/sup th/ order voltage harmonics by adding several series LC resonant loops into the DC link. As a result, the proposed 18-pulse rectifier can still meet IEEE 519 under abnormal source voltage conditions of the AC line. Theory analysis, simulation and experimental result are provided in this paper to verify the effectiveness of this method.
Electronically Steerable Parasitic Patches for Dual-Polarization Reconfigurable Antenna Using Varactors

This paper presents a dual-polarized reconfigurable antenna loading electronically steerable parasitic patches. The proposed dual-polarized antenna is surrounded by four parasitic patches each of which is mounted by two varactor diodes on the ground. By tuning the varactors, continuous two-dimensional beam-steering can be achieved for each of the polarization. A prototype of the proposed antenna is fabricated and measured. Excellent agreement between the simulated and measured results is observed. It is observed that the maximum beam-scanning angles in E-plane and H-plane are greater than ±25∘, which is suitable for 5G base station applications.
DIFFERENCES IN CHILDREN EMOTIONAL VALENCE RATINGS OF WORDS AND PICTURES

"Words and pictures stimuli are often used in study of perception, language, and memory. More and more studies are being done on how emotional words or pictures influence different cognitive processing. However, the emotional rating process of these stimuli has rarely been studied in young children. Especially, no study has investigated emotional rating process on pre-schoolers. This research examines how young children process emotional words and pictures stimuli. More precisely, we measured age (4, 5, and 6-years-old) and sex differences (girls and boys) in emotional valence rating of pictures and words. A corpus of 90 words and 90 pictures was selected from among the emotional databases compiled by Alario & Ferrand (1999), Bonin et al. (2003), Cannard et al. (2006) Syssau & Monnier (2009). This corpus was rated by 92 French children (28 four-years-old children, 16 girls and 12 boys; 34 five-years-old children, 14 girls and 20 boys; and 30 six-years-old children, 13 girls and 17 boys). These ratings were made using a three points emotional valence rating scale (negative, neutral, and positive) based on AEJE scale (Largy, 2018). To keep the rating task simple for the children, the scale labels were using drawings of faces. The 90 Words and 90 pictures were divided in sets of 15 stimuli. Each child rated all sets of stimuli in separate sessions. These sessions were in a random order between words and pictures stimuli sets. Good response reliability was observed in the three age groups. We assessed age differences in the valence ratings: Four-year-old children shown lower mean scores in valence rating (positive, neutral, and negative) than did five-year-old ones who shown lower mean scores in valence rating than did six-year-old ones. Despite a lack of consensus in the literature, we found sex differences in the valence ratings. Girls in each age groups shown higher mean scores in valence rating than did boys. Moreover, results shown a significant difference between pictures and words ratings. Children better rated words than pictures in each age group and sex. Besides, analyses revealed significant differences in emotional valence rating between negative, neutral, and positive words and pictures stimuli. Positive words and pictures stimuli were better rated by children than negative ones which were better rated than neutral ones. Future research will compile this corpus in a database, and it could become a worthwhile tool to control emotional verbal and visual stimuli in experimental design for children. "
Investigating CSR Practice And SERVQUAL Model For Customers’ Attitudinal And Behavioral Loyalty In Banking Context; A Sequential Mediation Model

The quality of service delivery is considered one of the most important success indicators in the banking sector. Therefore, this research aims to investigate the impact of corporate social responsibility (CSR) on the SERVQUAL model in the retail banking sector, taking into account the serial mediation of customer satisfaction and affective commitment. A sample of 313 retail banking customers was employed for the final analysis. The authors validate a measurement model using structural equation modeling (SEM). The findings of this research suggest that corporate social responsibility (CSR) has a significant relationship with SERVQUAL dimensions. Furthermore, results showed potential effects of SERVQUAL dimensions on customer satisfaction and affective commitment. Consequently, corporate social responsibility (CSR) has a strong indirect association with attitudinal and behavioral loyalty. The theoretical contributions of these results for managerial practices are also discussed.
COM-MABs: From Users' Feedback to Recommendation

Recently, the COMbinatorial Multi-Armed Bandits (COM-MAB) problem has arisen as an active research field. In systems interacting with humans, those reinforcement learning approaches use a feedback strategy as their reward function. On the study of those strategies, this paper present three contributions: 1) We model a feedback strategy as a three-step process, where each step influences the performances of an agent ; 2) Based on this model, we propose a novel Reward Computing process, BUSBC, which significantly increases the global accuracy reached by optimistic COM-MAB algorithms -- up to 16.2\% -- ; 3) We conduct an empirical analysis of our approach and several feedback strategies from the literature on three real-world application datasets, confirming our propositions.
Supervisory framework for threat detection withmultilayer processing in CNN

Face recognition has received huge acknowledgement due to its various uses in Internet communication, security, access control, surveillance, PC entertainment and law enforcement. Conventional methods of recognition based on the ownerships of identity-cards or full knowledge such as a security number or password are not totally solid. Physical ID cards can be lost or forged, passwords can be hacked or forgotten but a face is undoubtedly connected to its owner. It cannot be stolen, borrowed or easily forged. Our current system has a lot of weaknesses wherever it is simply taken and merged. The focus of this paper is to help users for development of the security by utilizing face identification and recognition. The proposed framework principally comprises of subsystems specifically picture capture, face identification and detection, email alerts and metal detection. Furthermore, the improvement in Computer Vision through Deep Learning algorithms has been an impressive achievement, especially with the Convolutional Neural Network algorithm. A convolutional neural network is a feed-forward neural network that is by and large used to break down visual pictures by using grid-like topology. It is also called as ConvNet. The objects in a picture are distinguished and arranged using convolutional neural network. CNN detects various simple complex patterns in images and data in its different layers of Convolution Layer, Max Polling Layer and Fully Connected Layer . This field intends to allow and configure machines to see the world as people do, and utilize the information for doing tasks (such as Image Analysis, Image Recognition and Classification, etc).
Comparative study of intrathecal bupivacaine and bupivacaine with clonidine to assess degree of sensory and motor effect and postoperative analgesia in lower limb orthopedic surgeries

Background: Subarachnoid blockade amongst regional anesthesia has been most commonly used for performing abdominal and umbilical surgeries. There is persistent search for finding an adjuvant to local anesthetics to prolong its action along with hemodynamic stability. In this study we have used clonidine as an adjuvant to local anaesthetic agent and have assessed its ability to prolong motor and sensory blockade and hemodynamic stability. Methods: This observational study was conducted on 56 patients of ASA grade I/II, undergoing lower limb orthopedic surgeries who were divided into 2 groups: Group B : Injection 3.0 ml hyperbaric Bupivacaine 0.5% + 0.12 ml normal saline was given intrathecally and Group C : Injection 3.0 ml Bupivacaine (0.5% hyperbaric) + 0.12 ml injection clonidine (20 mcg) was given intrathecally. We compared duration of sensory and motor blockade, hemodynamic changes, duration of analgesia and complications in both groups. Result: The onset of sensory and motor blockage was comparable in both groups. Duration of sensory and motor blockade was significantly longer in Group C than group B (P < 0.0001, P < 0.0001, respectively).
VOCAL SEPARATION FROM SONGS USING DEEP CONVOLUTIONAL ENCODER-DECODER NETWORKS

Nowadays, the Sound Source Separation(SSS) is an interesting task for Music Information Retrieval(MIR) researchers. Because it is related to many other MIR tasks such as singer identiﬁcation, singer veriﬁcation, and voice conversion. In addition, if we can separate clean vocal from songs, we can also make clean instruments by reversing phase. However, it is very difﬁcult to extract a clean source because a song includes a lot of sound. In this paper, we propose a Deep Convolutional Encoder-Decoder Networks (DCEDNs) based on U-Net model, compare the performance of vocal separation to this baseline model, and analyze more detail considerations for better performance.
Inductive and capacitive loaded miniaturized implantable patch antenna with circular polarization for bio‐medical applications

Implantable coaxial fed patch (ICFP) antenna with circular polarization operating at 2.45 GHz Industrial Scientific and Medical (ISM) Band is fabricated, measured in 500 ml mimicking gel and 1.3 Kg of chicken breast tissue used for biomedical applications. The miniaturized ICFP antenna is experimentally validated and reported in this research work. The volume of the ICFP antenna is 10 × 9.2 × 2.56 mm3 features a compact size by employing meandered slots on the patch, shorting pins and defective ground structure (DGS) on the ground plane for reducing the size and enhancing the bandwidth. Moreover, introducing circular ring slots and notches on both sides of the patch achieved the circular polarization. The results exhibit good matching between the coaxial feed and the proposed antenna. In this research, the implantable structure resonates at −10 dB S11with impedance bandwidth 200 MHz (2.35–2.55 GHz) and 200 MHz circular polarized–3 dB bandwidth is observed from 2.35 to 2.55 GHz. Additionally, the specific absorption rate (SAR) value analyzed as 0.98 W/kg in a three‐layered human tissue model.
Decision-making Aid for the Design of Reconfigurable Machine Tools

2 Abstract: Reconfigurable machine tools are proposed as manufacturing concepts coping with turbulent and quickly changing business environments. New tools for efficient modelling of different machine variants are required in order to facilitate and accelerate the re-configuration of machine tools. This paper presents a software based methodology for designing and evaluating the performance and conformance to requirements at an early stage. A machine model can be assembled by accessing a module library, which contains models of all available physical modules. The machine behaviour of the resulting configuration is tested, which provides reliable information on the physical machine properties. Different variants can be set up and quickly and easily analysed, significantly improving the data basis on which important and far-reaching decisions have to be made.
Indonesian Gastronomy (Volumes 1 and 2)

The books “Indonesian Gastronomy Volumes 1 and 2,” written by Professor Murdijati-Gardjito and colleagues, are interesting because they are among the first gastronomic books authored by experts in Food Science and Technology. While representing a coherent work, the two volumes focus on different aspects. The first one explains aspects of Indonesian culinary history at the national and global levels, including the changes that have taken place in the contemporary era. The second volume pays attention to the technical aspects of physical changes and chemical reactions in the food-making process. Volume 2 also describes Indonesian cuisine based on geographical location and ethnic affiliation.
Energy saving through solar lighting systems

Among the energy expenses for a building, the lighting system can contribute up to 50% of the total electrical consumption, and especially large quantities of energy are used in schools and office buildings. One possible method to reduce such consumption is to exploit solar, or natural, light. Through natural light, it is possible to illuminate indoor environments while maintaining appropriate illuminance levels necessary for indoor activities. Indeed, it is a mistake to search for the maximum energy savings, if this creates a possible disturbance to a person’s visual health in the office. Moreover, it is important to highlight that the light quantity is not enough to evaluate the working comfort; the light quality must also be held in consideration. Therefore, for optimal energy savings, the most favorable combination of the elimination of energy waste, the light quality, and the light quantity must be assessed. Key-Words: Natural light, solar light, energy saving, Daylighting, energy certification, insulation
