Abstract:

Chiller Compressor is used in a large plant where there is a requirement of bulk amount of chilled water supply. These machines are very costly and adequate protection of the machine needs to be ensured. The machine has certain sequences of operation which must be followed before the main compressor is given power. Even a minor mistake in sequence of operation may lead to a detrimental effect to the compressor whose repair cost as well as downtime is very high. A protection system has been designed to protect the compressor of the chiller machine to prevent it getting damaged due to any kind of mal-operation. Being heart of a chiller plant it is necessary to provide a good monitoring system. A SCADA based monitoring system has been provided for round the clock monitoring of the machine. A system has also been introduced utilised commonly available technology to get the performance analysis of the machine electrical parameters.

Abstract:

The production of marble generates a huge amount of waste powder during its manufacturing in Egypt causing an environmental problem. The utilization of this waste in concrete is a smart solution for this environmental problem. The behavior of concrete containing waste marble powder as a replacement of cement or fine aggregate was studied previously, but the present investigation focuses on studying usage waste marble powder on large-scale reinforced concrete beams' flexure behavior. For this purpose, a numerical model using ABAQUS is developed for a series of six reinforced concrete beams. The results were validated by an experimental investigation where six specimens were casted and tested. However, the study includes its effect on the concrete mechanical properties......

Abstract:

Logic gates are the fundamental components of any digital system and can be considered the "building blocks". A logic gate is a simple electric circuit consisting of two inputs and a single output. The most frequent names for logic gates are AND, OR, NOT, XOR (Exclusive or), NAND (NOT AND), and NOR. An OR logic gate begins with the provision of two electrical inputs. If one of the inputs has the value one or indicates that it is "on," then the output will also be one. In electronics, there is a type of logic gate known as an inverter or NOT gate. The report is broken up into five distinct parts or sections. The first section of this report covers the experiment's results on logic gates. They are used in the process of performing logical operations on one or more binary inputs to produce a single binary output. This article will examine the functions of the NOT, OR, and AND gates found in a logic circuit......

Abstract:

Standard machine tools can be converted into speciality machine tools with the help of jigs and fixtures. Jigs and fixtures continue to be employed, either alone or in conjunction with other technologies, despite the general trend toward higher quality production. Although several writers have provided valuable details on some aspects of fixture design, there is still a need for a unified approach to creating jigs and fixtures. This paper examines the fundamentals of fixture and jig design. These principles of location, clamping, and automation in fixture design form the heart of effective jigs and fixture design, which evolves irrespective of the rapid evolution of machine tools and manufacturing technologies. The ideal fixture would solve the workpiece distortion brought on by clamping and cutting force, in addition to the high productivity and machining repeatability it would otherwise provide..

Abstract:

The Triboelectric Nanogenerator (TENG) is an emerging novel approach to capture wind energy, particularly at low wind speeds. In this study a TENG of dimensions, 8 cm width, 2 cm thick and 12 cm in length was modelled. For a wind velocity of 1.5 m/s it was observed that the power that can be achieved was 15.25 mW/m3. On the other hand, for a high wind speed of 4.6 m/s, it was observed that the power achieved was 277.98 mW/m3. The use of this TENG has been demonstrated to extract power at the low wind speeds that traditional wind turbines struggle or are unable to produce power.

Abstract:

Geopolymer mortar is an environment friendly and promising alternative to cement mortar. Research were going in the field of geopolymer cement, geopolymer mortar and also geopolymer concrete. For the preparation of geopolymer mortar an activator solution and a source material is needed. Any material which is rich in silica and alumina can be used as a source material. Sodium silicate and sodium hydroxide or potassium silicate and potassium hydroxide is used as activator solution. Flyash, GGBFS, silica fume, sugarcane baggase ash etc are used as source materials. This source material and alkaline solution react together to produce the geopolymer mortar. One of the important physical property of concrete is its compressive strength. In this experimental research the effect of molarity of solution on the compressive strength of geopolymer mortar were studied. Also the effect of curing (ambient curing and oven drying) on compressive strength were also studie.

Abstract:

In this research, we discuss the situation of students in the three to eight year old age group. Every day in the Kingdom of Saudi Arabia during school days, more than 1,000,000 students are transported throughout the country by more than 15,000 school buses. Everything is dependent on the human element. During school transportation around the world, many children are forgotten inside the school bus and with many of them eventually going missing or even dying. The bus driver is usually busy and tired due to the focus on the road, which may make him lose focus on those on the bus. Therefore, we believe that modern technological development must intervene in order to protect children from this problem. In our research, we find a solution to the problem of children being forgotten inside the school bus, mostly due to falling asleep, and being exposed to problems that may cause them harm or death. Our solution to this problem is to verify school children get on and off the school bus safely, through the use of facial recognition and speaker recognition technologies.

Abstract:

Despite the documented evidence of benefits of sustainable construction practices, Nigeria still lags behind in adopting the concept. Several scholars and proponents of sustainability studies have argued for and against the adoption of foreign-based sustainable construction practices in developing countries. This study was conducted to assess the views of stakeholders regarding the feasibility of adopting a unique building rating system for Nigeria. Data for the study were collected through focus group discussions as well as a structured survey questionnaire. Data analysis involved both descriptive and inferential statistics. The findings revealed that the focus group professionals were very familiar with the concepts and practices of green building. However, most survey respondents who were educational institutional employees appeared to be less knowledgeable about green buildings. Further analysis of findings suggests that non-significant differences in opinion exist among the users of conventional buildings regarding the growth and development potential of green buildings in Nigeria..

Abstract:

The mammary gland is an organ that has an internal structure formed by lobules, ducts and ligaments that perform both physiological and mechanical functions. This structure aesthetically defines the body and has the additional function of producing milk in mammals to support offspring. Currently, structures and shapes are being studied to imitate the nature of the mammary gland for medical applications such as prostheses, systems and models for surgeries, the most used technique for this is biomimetics. There are no models or devices that contemplate the internal structure of the mammary gland, so in this work different structures that imitate the lobular adjustment found in a real mammary gland are proposed, these structures were subjected to different load states to numerically evaluate and optimize the proposed structures. It was found that the triangular or lobular structures have better behavior in the distribution of deformations and stresses being excellent candidates to be part of biomedical applications.
