The wireless hand gesture controlled robotic arm is a wireless system that can convey the information between two or more points and it is not physically connected by any electrical conductors. It will convey movement information from a real person’s hand to the robotic arm wirelessly. Some common controllers used to control a robotic arm system include mouse controllers, keyboard controllers, joystick controllers, keypad controllers and so on. Although all of these controllers are the most common controller to control a robotic arm system, there are still some difficulties to use these controllers. The objective is to ease the control of the robotic arm with hand gesture by using flex bend sensors and servo motors for humanitarian aid purposes. Two Arduino NANO is used, one on the real person’s hand and the other on the robotic arm as the microcontroller in this project since it is easy to change and the programming language of this microcontroller is more familiar rather than other microcontrollers. A pair of NRF24L01 transceiver module is used for the wireless communication between both Arduino NANO microcontrollers. This project results in a much easier and reliable controlling method of the robotic arm.

Seismic full waveform inversion (FWI) is a technique to build a high-resolution velocity model of the subsurface by iteratively minimizing the misfit between recorded and synthesized seismic data. However, classical FWI driven by gradient-based local optimization is vulnerable to local minima caused by lack of low-frequency components and an accurate initial model. Although global optimization methods such as genetic algorithm (GA) are less affected by the presence of local minima, those methods are affected by "curse of dimensionality." This results in low-resolution model less than optimum solution. Therefore, we propose an FWI method based on genetic local search algorithm with hybrid-grid scheme (HGLS-FWI). This method combines GA with coarse grid as a global search and gradient-based optimization with fine grid as a local search to directly deliver high-resolution model, while reducing the risk to be trapped in a local minimum. Our experimental results demonstrated that the proposed method reduced the average velocity estimation error by 62% compared with a classical gradient-based FWI on the condition that neither low-frequency components nor an accurate initial model was available.

Nowadays there are many asset sharing services provided by various companies worldwide. In the USA, 56.5 million people have used a sharing economy service at least once in 2017, and in China 600 million people were involved in the sharing economy in 2016. However, most of these services face the same problem, which is asset damage. They do not have ways to practically monitor their assets’ conditions. This paper describes the development of a system for the real-time monitoring of the shared assets. The system has built-in functions that allow the administrator to track the assets’ locations and motions in real-time, and it could initiate alerts when the asset has entered higher-risk areas or is undergoing abnormal motions. A GPRS module was used to send the sensed information to a remote server wirelessly. The system was tested by taking it to a predefined high-risk zone for 19% of the time, and by putting it in high-risk motion for 80% of the time. The system detected all the abnormal statuses successfully.

In this paper, we describe two setups of a wireless image distribution system using different network architectures. In the first setup, commercial grade network equipment was used in the network infrastructure of the system. In the other setup, the network infrastructure consists of a wireless mesh of NICT NerveNet nodes. For the first setup, results showed that the choice of hardware and network equipment used were sufficient to support the load of the system in an auditorium with a capacity of about 160 people. For the NerveNet setup, it superseded the first setup in terms of quick and clean setup, leaving the performance aspect to be further improved.

Information Governance (IG) decrease cost of operation, creates opportunity of new ventures, prepare liturgical evidence for litigation while committing to the information lifecycle process by abiding records management using proper and comprehensive information policy. In the meantime, IG enabling access and discovery using Information Technology (IT) infrastructure that restrict information based on privileges and perimeters with the embedment of information architecture while sustaining better business operation. Dark data is information, collected as a function of an organization’s normal operations but rarely or never analyzed or used to make intelligent business decisions. By IG means, dark data would dramatically increase revenue, growth and efficiency of a business and institution compared to their competitor who don’t take serious action on dark data. As a result, a Dark Data Management Model proposed comprises of 1 main core governance element, 4 main processes but defined by few activities. The model was proposed as generic approach on managing dark data since the process should be applied continuously not only to new receiving information but also stored data. Dark data mining process was not included in the proposed model as the model focus on the preventive measure which can be used to current data which falls under the category of dark data based on the value assessment of each organization.

A new methodology is suggested in this research to investigate some parameters of the pressure beneath the foot of healthy older adults. Using such methodology helps to accomplish human gait analysis in more efficient way. It allows reduction the resources, such as time, cost and efforts, required by the commonly used approaches to conduct human gait analysis. It also helps to achieve more accurate results.We recruit a small number of participants to collect data with higher accuracy for the purpose of reducing the resources, and then combining them with published data to satisfy the sample size conditions. Hence, the final results are computed from the combined data.The targeted parameters are maximum force (MF) and pressure time integral (PTI) from four regions of the human plantar, namely whole foot, rearfoot, midfoot and forefoot.Five healthy older adults were recruited to preform two sessions of trials by using 300E F-scan insole sensors. During each session, twelve walks by each participant along a 10-m walkway at a laboratory setting were recorded after wearing appropriate sized shoes with the sensors inserted inside them. We suggested the so-called mean of three steps protocol to extract the higher accurate self-captured data.To obtain the final results from the combined data, we use the so-called weighted mean and standard error.Our findings showed that the new approach comparing to the most commonly used ones leads to more accurate results using less resources. It produced smaller SE’s in all of the eight parameters studied.For the maximum force and pressure time integral, the results of this research indicated that: 1) the whole foot had the biggest values 2) the forefoot region had the second largest values and 3) the regions of rearfoot and the midfoot had the lowest last two values in decreasing order.

The energy storage system of many commercially available hybrid electric vehicle or pure electric vehicle is composed of only battery packs with a bidirectional dc-dc converter connected to the high voltage dc bus. In order to further improve fuel consumption efficiency, topologies to hybridize energy storage system for electrical vehicle have been developed. With these various combinations of energy storage, one common feature can be seen; which is to efficiently combine one fast response energy storage device with high power density and slow response device with high energy density. In relation to this, the Quasi Z-source inverter (qZSI) topology has gained attention as an alternative to the conventional voltage source inverter in many applications such as the electrical motor drive system. Apart from offering a single stage DC-DC-AC conversion, it offers a flexible way on how the hybrid energy storage can be introduced to the system. In this research, a new combination of battery/supercapacitor as HES with qZSI applied for the induction motor drive system is investigated. The effectiveness of proposed hybrid energy storage method in qZSI for the induction motor drive system is verified and validated via simulation and hardware experiment results where it is shown the battery current stress is reduced to approximately more than 50%.

Sine-Cosine algorithm (SCA) is an optimization algorithm formulated based on mathematical Sine and Cosine terms. It is widely used to solve various optimization problems. However the algorithm performance in terms of accuracy is not at optimum level. This paper presents an improved SCA with a new adaptive strategy based on an exponential term. The exponential term is adopted to establish a relationship between searching agents step size and fitness cost. The agents step size is exponentially changed due to the change of the fitness cost. The proposed algorithm is tested with a set of benchmark functions in comparison to the original SCA. A statistical analysis of the algorithms performance in terms of their accuracy is conducted. A Wilcoxon Sign Rank test is adopted to check significance level of the proposed algorithm as compared to the original SCA. Based on the simulation conducted, the adaptive strategy has resulted a significance improvement of the accuracy and convergence speed.
