This paper is devoted to study a fractional equation involving Caputo-Katugampola derivative with nonlocal initial condition. Unlike previous papers, in this paper, the source function of problem is assumed having a singularity. We propose some reasonable conditions such that the problem has at least one mild solution or has a unique mild solution. The desired results are proved by using the Banach, Leray-Schauder and Krasnoselskii fixed point theorems. Some examples are given to confirm our theoretical findings.

In this paper we discus on a Lyapunov-type inequality for a fractional differential equation involving sequential generalized Caputo fractional derivatives with boundary conditions. The results presented in this paper is new to the corresponding results in the literature.

Performance-related pay (PRP) is an integral part of Reward Management (RM) and is considered to have beneficial effects on organisational performance and employee motivation. Drawing on 14 case studies, this paper examines the Reward Management practices of local and multinational companies in Australia with specific consideration to PRP within the debate over the applicability of the transfer of the Human Resource Management (HRM) practices between nations through subsidiary-parent company relationships. After reviewing the relevant literature(s), the study concentrates on finding whether multinational corporations (MNC) in Australia pursue similar or different RM practices compared to their domestically owned Australian counterparts with special reference to PRP. It also investigates whether there are national variations between multinational companies in terms of the nature and character of their practices. The findings reveal country of origin differences in the way PRP practices are applied in subsidiaries of foreign-owned companies in Australia and local Australian firms. The case studies are used to examine and explain the practices.

It is very common to stabilize the preset value (Wanted value) of analog signals such as temperature, pressure, weight, flow, speed in automatic control. However, these control objects often have some problems such as overshooting, taking a long time to bring the system to a steady value, and large errors. One of the most used systems to overcome these problems is the PID, which is a preset stabilizing system with a quick function that returns the system to the set value in a short time without overshooting. error is close to zero. However, determining the scale parameters Ki, integral Kp, and differential Kd for the system to work optimally is a problem that needs to be studied. This paper presents how to accurately determine differential, integral, and scale coefficients according to 3D virtual reality model. Used a lot in simulation modeling for training and practical applications.

Naringenin is a member of the flavonoid family. This natural compound represents a large proportion of secondary metabolites produced by higher plants and is a rich part of the human diet. Naringenin also has been used in the pharmaceutical and medical fields as an effective drug for anti-oxidative, anti-cancer, anti-obesity, and anti-inflammatory activities. Naringenin is also a typical plant metabolite, that has never been reported to be produced in prokaryotes.

This paper analyzes the interpersonal metafunction in text messages of teachers of English at Viet Anh School. The paper uses Systemic Functional Grammar as the theoretical framework which aims to investigate into a language from a qualitative approach. The aim of this paper is to discover how interpersonal metafunction is being served in text messages of teachers of English in terms of mood, speech function, modality and personal pronouns. The analysis indicates that the English teachers often use text messages for providing more information and demanding services by the dominant use of declaratives clauses in their interaction. These English teachers also perform their plans or desires about their future intention through the frequent use of modality such as ‘will’, ‘can’ or ‘could’. Through the analysis of personal pronouns, it can be clear that the English teachers tend to interact with each other by sharing their points of view rather than mentioning about other things or persons. Their social relation is shorten through the popular use of pronouns ‘I’, ‘we’ and ‘you’. Thus, it can be concluded that the social relationship among the English teachers is established and maintained through the use of interpersonal metafunction.

Heavy metal pollution is a major problems in the environment. The impact of toxic metal ions can be minimized by different technologies, viz., chemical precipitation, membrane filtration, oxidation, reverse osmosis, flotation and adsorption. But among them, adsorption was found to be very efficient and common due to the low concentration of metal uptake and economically feasible properties. In this review paper, Fe–Mn binary oxide incorporated into diatomite (Fe/Mn-diatomite) was prepared by a simple coating method , and removal of Cu(II) from aqueous solutions. The effects of three independent variables including initial ion concentration, removal time, and adsorbent dosage were investigated on the maximum adsorption of Cu (II). The optimum conditions for the adsorption of Cu(II) was obtained: 75 ppm of initial ion concentration, 150 min of removal time and 1.5 g/l of adsorbent. The maximum removal efficiencies of Cu(II) was obtained 86.25%. The results showed that Fe/Mn-diatomite was apable of treating copper metal in wastewater.

The paper demonstrates the role of globalization and localization in the process of Vietnam’s interaction and integration with other cultures, causing changes in Vietnamese language. Globalization is defined as the free movement of goods, services and people of the worldwide scope across the borders of countries, resulted from the opening up of the global economy and advances of technologies. The increasing interconnectedness and integration of the economies of the world furnish more influx of information among countries which do not have anything in common and Internet and social media well contribute to such spread. Not only the pros but the cons of globalization are used to explain the part of localization as the entire process of adapting a product or content to a specific location or market. The paper indicates localization as the Vietnamese people’s endeavor to adapt Vietnamese language to the world while protecting and enhancing the national characters. The differences between localization and globalization are analyzed to demonstrate the value and requirements of localization in the present time. The influences of Sino-Vietnamese and French language are also found out as evidences of the phenomena. The changes of Vietnamese language from globalization and localization are illustrated with devices, ideas and images referring to the objects, actions or ideas.

This paper examines the main challenges of the processes of space and social policy change present to current urbanization trends of Taiwan. The chapter argues that one of the main challenges is economic growth, increasing integration into the global economy and making Taiwan competitive in the global economy. This process leads to the growth of large urban regions that present many challenges to the urban development in the future. In particular, the paper focuses on the most fragile areas of the extended urban spaces are the rural and urban margins, where urban activities are expanding into densely populated agricultural regions. It is argued that in these areas, local policies should be developed that adapt to local ecosystems. The paper presents lessons of interventions in this field for Ho Chi Minh, Dong Nai and Binh Duong Region for urban expansion.

Youth in a nation is the most viable and potential human resource in both demographic and social structure. Without the youth's adequate and integrated bio-social development a nation cannot attain its anticipated human goals. Based on government initiative a2i, the empowerment of youth towards sustainable development in Bangladesh is described in this paper. Although the Bangladesh Government has formulated and implemented policies, plans and programs for youth welfare are still through GOs and NGOs. Related literature indicates that, regardless of all age and regions, young people in this country face several socio-cultural problems where they cannot grow and empower themselves adequately. As a result, they cannot play their important roles in sustainable development and changes within the country. To resolve the problems of the youth in relation to their development and empowerment, the Government of Bangladesh is developing and implementing some solutions. The case study focuses on the role of a2i for development of youth in the successful design of public development and sustainable development programs.

Activity recognition is one of the preliminary steps in designing and implementing assistive services in smart homes. Such services help identify abnormality or automate events generated while occupants do as well as intend to do their desired Activities of Daily Living (ADLs) inside a smart home environment. However, most existing systems are applied for single-resident homes. Multiple people living together create additional complexity in modeling numbers of overlapping and concurrent activities. In this paper, we introduce a hybrid mechanism between ontology-based and unsupervised machine learning strategies in creating activity models used for activity recognition in the context of multi-resident homes. Comparing to related data-driven approaches, the proposed technique is technically and practically scalable to real-world scenarios due to fast training time and easy implementation. An average activity recognition rate of 95.83% on CASAS Spring dataset was achieved and the average recognition run time per operation was measured as 12.86 mili-seconds.

In this paper, we first introduce a new class of bilevel weak vector variational inequality problems in locally convex Hausdorff topological vector spaces. Then, using the Kakutani-Fan-Glicksberg fixed-point theorem, we establish some existence conditions of the solution for this problem.

The paper presents general theory about making small models for studying large machines. Here, the author refers to the design of pile driving and pressing machines. To express ideas, the author presents design drawings presented in three-dimensional perspective. Currently, pile drivers and pile presses are two separate machines, in which their base machine is the same, their working parts are slightly different. The author takes advantage of the slight differences to combine them into one machine, so as to ensure that this machine is able to pile or pile. In addition, the structure of pile making and pressing machines is created by the author, which is somewhat simpler than the current construction and driving machine. This successful study will form the basis for manufacturing a pile driving machine and pile machine into a single machine, greatly reducing the costs of procurement and construction machine use.

Variable Frequency Drives (VFDs) are electronic power controllers that allow for accurate control of the speed of alternating current (AC) induction motors that used in many kinds of machines including fans, pumps and compressors. These motors are used in most heating, ventilation and air-conditioning (HVAC) systems and account for a significant percentage of the total HVAC energy consumption. More efficient operation of these motors using VFDs can result in significant energy savings. Besides, the communication between VFDs and PLC for Supervisory Control And Data Acquisition (SCADA) is also important. Modbus protocol has many kinds as RS485, RTU, Profinet,...In this paper we will present the communication between a PLC Siemens S7-1200 and an ATV310 Drive (Schneider) via Modbus RTU protocol which is supported.

Across the world, the first accounting course provides serious challenges for teaching. These arise from powerful negative perceptions which include the anxiety associated with tertiary-level study and the differing backgrounds or majors of students required to take the course. This paper outlines some examples of nontraditional teaching techniques and highlights how the course could be best structured to overcome such negative views while at the same time responding to the changes in the industry. The design and content of the proposed course emphasizes the USER approach and is directed to English as second language learners. This is a case study in an Australian offshore campus and is the end result of the progressive improvement in the structure and delivery of the course.
