Abstract:

The article presents the results of experimental studies of two types of nailed connections on metal plates: compounds without sleeves and joints modified with pressed fiberglass sleeves; Recommendations for the calculation of nailed connections with sleeves have been developed. The tests used mathematical planning methods of the experiment, which allowed to significantly reduce the number of test samples of compounds and to obtain a mathematical relationship as a response function for the condition load effect factor  , taking into account the increase in the bearing capacity of the nailed connection due to the presence of a pressed fiberglass sleeve, from three factors: the angle between the direction of the current force and the direction of the wood fibers, the diameter of the dowel and the wall thickness of the glass-plastic howl sleeves. The dependence obtained allows us to determine the coefficient values  ​​for the nailed connections with bushings, without testing. In accordance with the plan of the experiment, 15 series of compounds were tested with pressed-in fiberglass bushes and 9 series of traditional nailed connections without bushings. According to the test results, the authors determined the destructive loads for two types of connections  соединенияand ; loads and   corresponding to the upper boundary of the elastic behavior of the connection; determined the coefficient of condition load effect factor   experimentally and obtained a mathematical relationship to determine the coefficient of condition load effect factor ; The bearing capacity of the nailed connections with pressed-in fiberglass bushes has been evaluated; A comparison of the deformability of the two types of joints was made, a method was proposed for finding the calculated bearing capacity of nailed connections with sleeves, recommendations were developed for making calculations for nailed connections on metal plates with fiberglass sleeves pressed into the drift sockets

Abstract:

The virtual tour is a simulation of a reallocation made with media like panoramas, image, text and etc. Virtual tours allow users to experience and see the location without visiting there. For example, instead of physically visiting to a country, user can sit back and virtually explore the country using their electronic devices. Many students not able to visit The National University of Malaysia campus before register themselves due to distance, time and maybe financing problem. There are many universities offer campus virtual tour visits to the students; University of Maryland, Taylor’s University and etc. The National University of Malaysia (UKM), Bangi campus has a huge infrastructure, it is hard for people unfamiliar with the campus to find their way around and they can get lost in the campus. An assistance from a simple tool can help visitors to navigate from one point to another. In this paper, a mobile application – UKM Explorer which used virtual reality technology to provide users with a simple platform for navigating locations prior to or subsequent to entering UKM using GPS technology is proposed. Beside provides a virtual tour of UKM campus through the panorama images of the point of interests. This application also offers the ability to search and pinpoint the exact locations of the point of interest such as the faculties, student accommodations, management buildings and other facilities in the campus.

Abstract:

Computational and Numerical Analysis is one of the core topics for Computational Mathematics in Engineering Mathematics. Students required to learn different methods of analysis as well as MATLAB programming to solve a given problem. The objective of this paper is to analyze the final exam questions of Computational and Numerical Analysis subject. There are four course outcomes for the Computational and Numerical Analysis subject. Five questions were set for final and each question carries 20 marks. The Bloom Taxonomy for the questions are from comprehension, application, analysis and synthesis level. A total of 115 students from Chemical Engineering and Mechanical Engineering departments took the final examination. To analyze this subject, the results of the final examination of students from Chemical and Mechanical Engineering departments are tabulated in EXCEL and transformed into WINSTEPS. The Computational and Numerical Analysis questions can be categorized into four groups. They are difficult, mediocre, easy and very easy. The ability of the Chemical and Mechanical Engineering students cannot be divided into any group. A misfit item is identified from Point-Measure Correlation, Outfit MNSQ and Outfit z-Standard. Since one item is out of the three measures, therefore there is one misfit question for the Computational and Numerical Analysis final examination. The person-item distribution map showed the questions which belong to difficult, mediocre, easy and very easy group. Generally Course Outcome 1 was difficult for the students. This question is from the analysis level from Bloom Taxonomy. Course Outcome 2 was average and Course Outcome 3 was easy for this batch of students. The Rasch model able to classify the difficulty level of questions versus the Course Outcomes of Computational and Numerical Analysis subject.

Abstract:

Over the past few decades, massive quantities of solid wastes are being produced from the red pitaya fruits by the food and beverage industries and their disposal leads to severe environmental issues. Despite being waste materials, the red pitaya’s by-products such as peels, seeds, and pulps are rich in beneficial active ingredients with diverse functionalities. Besides, the sophisticated technological advancements available today contribute greatly to the development of a variety of processes to convert these waste materials into high-value bio-products of excellent qualities. This review will be focusing on the potentialities and the current use of extracts and chemical constituents of the red pitaya and its by-products in the cosmetic field as antioxidants, natural coloring, moisturizing, anti-aging, and anti-inflammatory agents. These types of plant-derived actives are efficacious, economical and bio-sustainable, and therefore are theoretically suitable to substitute artificial and synthetic active ingredients, more customarily incorporated in cosmetic formulations.

Abstract:

In recent years, oil palm is one of the natural fibre being researched and tested to be used as an acoustic absorber. Experiments have been conducted on different parts of oil palm tree such as Empty Fruit Brunch (EFB), Oil Palm Frond (OPF), Oil Palm Trunk (OPT) and so on. This paper specifically discusses the analysis of the OPT fibre as a function of the sound absorber in densities of 120 kg/m3, 140 kg/m3, 160 kg/m3 and 180 kg/m3 with thicknesses of 10 mm, 14 mm and 18 mm. The OPT natural fibres were fabricated using method of Low-Density Fibreboard (LDF). The results show prominent Sound Absorption Coefficient, SAC (α) values for sample with thickness of 10 mm and 14 mm at frequency range of 3500 Hz to 6400 Hz for all densities except for sample with density of 180 kg/m3. As the thickness and density increases, the resonance peak shifted to lower frequency due to lower perforation exist within the sample which decreases the value of the absorption value. In comparison between the density and thickness, optimum and best result were produced by the sample with thickness and density of 14 mm and 120 kg/m3, respectively, where the SAC (α) value is around 0.93 at wide frequency of 3500 Hz to 5500 Hz. Nevertheless, sample density of 180 kg/m3 also exhibits similar behavior but with lower SAC (α) value and the maximum absorption value of 0.50 over the frequency range of 2500 Hz to 6400 Hz for all the thickness.

Abstract:

After joining the European Union, Romania benefited from over € 8 billion in funding for 2007-2013, plus national co-financing, funds that had to be directed to rural areas and agriculture to solve the multiple problems with which they are facing. To this end, in the present paper I proposed to analyze the impact of the implementation of measures under the National Rural Development Program on agricultural holdings in Romania during the programming period 2007-2013. I analyzed the situation of agriculture: the rural population and human resource, the number and size of farms and the average size of farms, then briefly presented the measures 141 and 142 for the restructuring of agricultural holdings through the National Rural Development Program 2007-2013 and finally we highlighted the impact of Measures 141 and 142 at the end of the 2007-2013 programming period as well as the extent to which the objectives of these measures were met.

Abstract:

Flash flood happens when the drainage or river could not cope with the sudden increase in rainfall volume. In Malaysia, flash flood often occurs in the developed cities such as Kuala Lumpur and Kuantan. Water yield or reservoir storage is the collection and storing of water during high-water period and to be used during low-water period. It preserves the excess water where or else it will result in water wastage and potentially cause a flood disaster to happen. The capacity of the water yield has to be sufficiently large to sustain the amount of increasing rain water without overflowing. The study aims to investigate the rainfall runoff relationship of Sungai Pahang River. Study period of this hydrological modelling was selected from year January 2013 to December 2017. The hydrological modelling using HEC-HMS of Sungai Pahang resulted with a correlation of 0.65 and Nash-Sutcliffe coefficient of 0.41. Clark unit hydrograph in transform method and recession constant in baseflow method have great impact on the simulation result.

Abstract:

Water is one of the most important elements required by all living organisms. However, uncontrolled developments and human activities have significantly affected the water quality in the river. Excessive nutrient discharge into the river will lead to many problems such as eutrophication, apart from disturbing the water supply. This study has been conducted to determine the nutrient concentration and nutrient loads in the Langat River Basin in terms of total phosphorus (TP) and total nitrogen (TN), as well as their relationship with the rainfall.  Four stations from the Langat River Basin upstream have been selected for this study. The water samples were collected weekly for six months spanning both dry and wet seasons. Two standard methods for examination of water and wastewater were chosen to determine the TN and TP concentration in the water sample. Method 8190 was used for TP while, TN was measured using Method 10071. The results showed that the nutrients in the water bodies generally were influenced by the land use, climate and stream flow of the river. The TN concentration for all four stations were within the USEPA limit. On the contrary, the TP concentration for all stations exceeded the USEPA limit, indicated that limiting nitrogen condition might happen and triggered algae bloom.

Abstract:

Titanium oxide () is used as photocatalyst. It has wide band gap of 3.2eV, so it can absorb only ultraviolet light. In this paper, we tried to make visible light response for  by doping Ni using Sol-Gel method. For photocatalyst experiments (methylene blue degradation), we made some sample types from handmade  powder, handmade Ni-doped  powder, and commercially  powder (P25).  Based on experimental results, the Ni-doped powder mixed with P25 powder can absorb the low range of visible light, as a result, it achieved highest methylene blue degradation ability.

Abstract:

Today, energy production problem is seriously in the world. Wastes is one of the renewable energy resources, it is converted to electrical energy by Microbial Fuel Cells (MFC).  In this study, a chamber-less MFC was constructed by some acrylic parts, electrodes and a filter paper-based proton exchange membrane (PEM). Bacillus subtilis was incubated and fixed on activated carbon sheet. To replace chemically treated PEM, Vaseline was used to treat the paper-based PEM. To increase the output, multiwall carbon nanotube (MWCNT) liquid was used to glue the cathodic electrode and filter paper-based PEM. Current density and power density were measured. Maximum current density and power density were 55 and 3.86 , respectively. Internal resistance of MFC was estimated between 5kΩ and 10kΩ based on the polarization curve.  Vaseline-treated paper-based membrane and MWCNT gluing method had positive effectiveness on the performance of the chamber-less MFC.
