Investigation of Formation Control Approaches Considering the Ability of a Mobile Robot

10.11591/ijra.v7i1.pp18-38
Hannes Wind , Oliver Sawodny , Thomas Br•aunl
This work investigates and compares various formation control approaches for mobile robots. A comprehensive literature review was conducted, with particular focus on the approaches' applicability to be implemented on real mobile robots with limited hard and software capabilities. A realistic model of mobile robots is introduced and its parameters are identi ed with measurements from actual mo-bile robots. Later on, the model is extended and used within simulation studies of the various investigated approaches. A collision avoidance controller based on a formation controller is proposed and simulations are carried out. Experiments on real mobile robots are conducted for two formation controllers and for the pro-posed collision avoidance controller. It is shown that if the requirements resulting from the simulation studies are satis ed, an implementation on the real robots is possible.

This study aims to evaluate the effect of the frequency of playing a board game that simulates entrepreneurial experience called “Traders” on the university students’ resilience and self-esteem. Traders Board Game (TBG) was developed in 2015 with an aim to improve several entrepreneurship skills among young adults, and resilience being one of them. Pre and posttests of resilience have been done to 12 participants before they were divided into three groups: the control group, who did not play the game, the experimental group A, who played the game once a week for three weeks, and the experimental group B, who played the game twice a week for three weeks. Resilience was measured by adapting Connor-Davidson Resilience Scale, whereas self-esteem was measured by utilizing Mruk two-dimensional Self-esteem scale. There was a statistically significant difference among the the three groups in resilience improvement, where the experimental group A scored the highest, and no significant difference was discovered in terms of self-eteem improvement. The results suggested that playing TBG in certain frequency significantly improves resilience among the participants.

Power Harvesting Using Piezoelectric Shoe For External Power Storage

10.11591/ijeecs.v9.i3.pp655-659
Mohammad Saffri Mazalan , Roslina Mohamad , Murizah Kassim , Shahrani Shahbudin
The demands for portable energy source have increased because most portable electronic device needs the extra energy throughout the day due to the user’s increase in power consumption. Hence, a piezoelectric power harvesting shoe circuit with storage mechanism capabilities is designed by using piezoelectric disc material, 1N4007 bridge rectifiers, USB cables, and an external power storage. Piezoelectric disc material of 27mm and 35 mm in size that produces AC voltage when applied pressure is embedded in shoe’ insole and the output AC voltage is converted using a bridge rectifier for each material. The output is connected to a USB cable and can be connected to the external power storage during power harvesting. Different sizes of piezoelectric disc produce different amount of voltage and are also affected by the pressure applied to it. An amount of 5V is the requirements needed to charge an external device. The 27mm disc produces a voltage of 3V to 5V depending on the pressure applied while the 35mm disc produces 4V to 6.2V. Piezoelectric disc material is an alternative way to harvest energy when embedded to a shoe with an added storage capability as it solves the problem of needing the extra energy for electronic devices.

Effort of NGO in Promoting Comprehensive Sexuality Education to Improve Quality of Life among Local and Refugee Communities

10.11591/ijere.v7i1.11237
Yeo Kee Jiar , Shih Hui Lee , Lina Handayani
Federation of Reproductive Health Association, Malaysia (FRHAM) is a pioneer Non-governmental Organization (NGO) in disseminating the knowledge and services of sexual reproductive health in Malaysia. A qualitative case study research design was employed to explore the roles of FRHAM in promoting Comprehensive Sexuality Education (CSE) for the well-being of locals and refugees’ communities. In-depth interviews were conducted with the staffs of FRHAM to inquire about their effort in delivering their services. The interviews were recorded, transcribed, coded and emergent themes were identified. FRHAM had played a part as educator, service provider, advocate and actively involved in improving the quality of life among the refugee community. The organization had developed modules for CSE and conducted programs for dissemination of knowledge. They also collaborated with local governmental agencies and other NGOs to promote awareness and utilization of services among the communities. Nevertheless, promoting CSE had experienced many challenges in Malaysia. The perceptions of Malaysian viewing sexuality education as taboos, cultural factors, the reluctance of educators in delivering, and the low visibility of FRHAM are the barriers encountered by FRHAM in promoting CSE. FRHAM recommended including parents, teachers and other stakeholders in the promotion of CSE and acknowledging CSE as an official subject to be implemented in schools.  The information from this study may encourage more partnerships between the stakeholders, policy makers and NGOs for providing high quality CSE and sexual reproductive health services.

10.11591/ijeecs.v9.i3.pp637-642
Norsyela Muhammad Noor Mathivanan , Puzziawati Ab Ghani , Nor Azura Md.Ghani
The size, structure, and composition of a population are affected by the fertility rates at any point of time. Many researchers took the opportunity to exploit the fertility rates in obtaining better fertility patterns for their country. The curve for the age specific fertility rate is consistent, and this feature allows the curve to be matched with a mathematical model. This paper aimed to identify the best mathematical model that fits the recent age specific fertility rate in Peninsular Malaysia. This study fitted the fertility data of Peninsular Malaysia from 1996 to 2014 to the four mathematical models, which were Hadwiger, Gamma, Beta, and Gompertz models. From the comparisons of the four models, it was found that the best fitted mathematical model is Hadwiger model. In relation to the data of early 21st century, there was an inclination for the best fitted mathematical model from Hadwiger model to Beta model. Hence, the best mathematical model for each year can be used to convert a fertility schedule classified in a five-year age group into a fertility schedule for a single-year of age in Peninsular Malaysia. This model also can be helpful for population projections by using limited and defective data.

Prospect Convenient Steadfast Procedure in Wireless Sensor Network

10.11591/ijeecs.v9.i3.pp613-615
Jewan Singh , Vibhakar Mansotra
This article objective is to improve the steadfast routing in Wireless Sensor Networks with little interfering and avoid packet collision. In the scheme, the entire node has the option of electing next Data Communication Node (DCN). The next data communication node is chosen depend on the intensity of link, remaining energy, and the node with distance towards the Base Station. Thus, the sender node transmits the information to the best DCN. Instantly, the DCN sends the acknowledgement (ACK) along with the number of packets received back to the node from which it obtains the data. The sender node assures the delivery of the transmitted packets by comparing the value of number of packets sent with the value obtained with the acknowledgement. If they are equivalent, it will send the verification identity to the DCN. If it is not equivalent, it will decide another node with highest link intensity. After that, the data chooses the DCN and repeat the process until the data reaches the Base Station.

Safiriyu Ijiyemi Eludiora , O R Ayemonisan
Nigeria official languages are English, Yorùbá, Igbo and Hausa. The focus of the study reported in this paper is to develop learning tool that can assist learners to learn the Yorùbá language using its alphabets. The study is critical to Yorùbá language, because of its endangerment. There is need to introduce different learning tools that can mitigate its extinction. A Yorùbá word perfect system was developed to assist people in learning the Yorùbá language. English and Yorùbá words formation are experimented using computational morphological approach (word formation). The theoretical framework considered Finite state automata (FSA) to realise different ways of combining the consonants and vowels to form word. Two to five letter words were considered. The system was designed and implemented using UML tools and python programming language.The system will teach the users on how the words are formed, and the number of syllables in each word. The user  need not to know how to tone mark word before he/she can use the system. Any word typed will be analysed according to its number of syllables. This approach produces representatives of all parts of speech (POS) of the two languages. It produces corpora for the two languages

10.11591/ijeecs.v9.i3.pp591-594
K. Gugan , S. V. Saravanan
In the field of Digital signal processing (DSP), the reduction of some logical elements counts is one of the main considerations. To minimize the area, computational delay, and power, the digital form FIR filter is to be implemented. The optimization of the ATP (Area, Time and Power) is achieved by using the efficient multiplication and accumulation unit (MAC). In this work, the direct form FIR filter with the efficient MAC unit is presented. At the initial stage, the half adders and full adders are to be modified by the reduction of the logical gates. The modified half and full adder are implemented in the Wallace tree multiplier for performing the efficient multiplication process. Carry save adder is divided into the two stages to reduce the computational delay of arithmetical operators. The proposed MAC design is implemented in the direct form FIR filter by using the HDL language.

10.11591/ijai.v7.i1.pp19-32
Sunil Kumar Srivastava
Artificial Intelligence (AI) is likely to transform the way we live and work. Due to its high potential, its adoption is being treated as the fourth industrial revolution. As with any major advancement in technology, it brings with it a spectrum of opportunities as well as challenges. On one hand, several applications have been developed or under development with potential to improve the quality of life significantly. As per a study, it is expected to double the annual economic growth rate of 12 developed countries by 2035. On the other hand, there is a possibility of loss of jobs. As per the available reports, the loss of jobs during the next 10-20 years is estimated to be 47% in the US, 35% in the UK, 49% in Japan, 40% in Australia, and 54% in the EU. In the era of globalization, no country can isolate itself from the impact of the advances in technology. However, the benefits can be maximized and losses can be minimized by putting necessary infrastructure and policy in place. Though several countries have decided their strategy for AI, India has not yet formulated its strategy. The report reviews the international as well as national scenario and suggests way forward for India.
