The complexity in housing affordability issue requires more consideration beyond mere economic viability. To increase life quality and well-being, the percentage of income spent on rent by individual household is essential for consideration. This study attempts to evaluate low income affordability level in Ado-Ekiti, Ekiti State Nigeria. A structures questionnaire was used to obtain data while analysis was done through Statistical packages for social sciences (SPSS). The outcome of the analysis indicated that a larger percentage of the targeted population spends above 30% of their monthly earnings on housing services. This relate with the benchmark set by several scholars, where authors maintained that a cost burden will exist where households spend above 30% on their housing services. This paper then concludes that majority of the dwellers in the study area experience a cost burden as they spend a large percentage of their monthly income on house rent. Hence this adversely affect their ability to meet other living expenses like medical bills, education, clothing, food and son on. Some recommendations are been suggested to improve the low-income housing affordability standard both within and outside the study area.

Cobalt chrome molybdenum (CoCrMo) alloy is among the biomedical materials which is considered difficult to cut materials due to their combination of high strength, high toughness, high wear resistance, and poor thermal conductivity. In this study, high speed end milling (HSEM) was performed experimentally to access the machinability of CoCrMo alloy using solid coated and uncoated tools at different cutting speeds of 125, 140 and 155 m/min under the minimum quantity lubricant (MQL) strategy. The axial and radial depth of cut were kept constant 4 mm and 1.5 mm respectively throughout the machining tests. The tool wear, tool life and tool wear mechanism were recorded and analyzed accordingly. It was observed that higher cutting speed significantly reduces the tool life due to rapid tool wear. Coated carbide tool performed better than uncoated carbide tool in terms of tool life for every cutting speed. It was also found that chipping, adhesion and cracks were the dominant wear mechanisms occurred on the cutting edge when high speed end milling of CoCrMo biomedical material.Cobalt chrome molybdenum (CoCrMo) alloy is among the biomedical materials which is considered difficult to cut materials due to their combination of high strength, high toughness, high wear resistance, and poor thermal conductivity.

Bentonite and marconite are commonly used as soil substitute and filler material for electrical grounding applications in trouble environments. Bentonite is a fine grained highly plastic clay derived from volcanic formation, whereas Marconite is an engineered material in the form of super conductive aggregate derived from coal power production. Both material are used to reduce the electrical resistance between the soil and earth-electrode rod. In this study, a sodium based bentonite, namely MX80 bentonite and Marconite aggregates were characterized and tested to perform as grounding material under varying water contents. After each test, the resistivity of each specimens were measured using a Nelsson 2-point resistivity meter. In addition, aluminum discs were inserted into the specimens to measure the effect of wetting and corrosion induced by both material. Test results indicated that the resistivity behavior of bentonite is greater than that of Marconite. On the contrary, the resistivity of Marconite is far lower than that of MX80 bentonite. The lowest resistivity achieved by Andrassy bentonite was found to be 2.4 Ωm under very wet conditions as compared to 0.44 Ωm in Marconite. Based on the tests results, the resistivity behavior of bentonite is governed by the water content. Water within the pores acts as particle bridging for electrical currents to pass through the bentonite. The resistivity values is lower under liquid state as compared to under plastic or solid state. On the hand, Marconite resistivity behavior remained somewhat unchanged under both dry and wet conditions indicating that interparticle contact is more dominant. Higher corrosion was observed on aluminum discs placed within bentonite specimens due to the availability of water.

This paper presents a portable Registered Jack 45 (RJ45) tester system using a smartphone. The design tester is portable and can be used to test the RJ45 cable. This system can be used to help the network engineer or technician to carry out cable installation and troubleshoot in the telecommunication room. It is used to identify the faulty cables before or after the network installations and also used for installation troubleshooting. Also, it is applicable to avoid any mistakes while connecting the RJ45 to the network cable since all RJ45 units are identical. Basically, this system is comprised of three particular units which are the smartphone, Arduino microcontroller and Android studio software. The Android studio used in this system acts as the main programme while the Arduino acts as the subordinate programme. An Android application is installed in the smartphone to send the message to Arduino to check and test the connectivity of the cable which uses the RJ45. Then, the data is sent back to the main software to determine the cable types of RJ45. The prototype tester has been tested in multiple testing setting and are shown to be able to successfully recognise the cable types.

Time based control loop in digital algorithm could be accomplished through built-in circuits such as watchdog timer or external device that known as Real Time Clock (RTC). Another option which is simple, fast and easily implemented is by using free run internal coding interval. The accuracy is not as good as compared to RTC but it simplifies a lot of work especially setting up time during interfacing hardware between microcontroller and RTC. Those who experience with the intermittent work with RTC, escaping the choice with something else is always triggered in mind. RTC is good but the process of activating the device must be properly done through hardware and software. Hence this problem initiates a very simple technique that could be used to replace RTC by using free run internal coding. Microcontrollers need 4 clock cycles to execute one line of assembly code. In a simple free control loop for instance 100 assembly codes, it will consume 5 us to complete the execution in 8 MHz oscillator. As long as the time taken to complete a loop is less than a second, the free run loop coding is executed to function as pendulum in mechanical clock. The result from this work shows very marginable run time error and the most important issue is simplicity of constructing the time base circuit gives a very good option.Time based control loop in digital algorithm could be accomplished through built-in circuits such as watchdog timer or external device that known as Real Time Clock (RTC).

Hence this problem initiates a very simple technique that could be used to replace RTC by using free run internal coding. Microcontrollers need 4 clock cycles to execute one line of assembly code. In a simple free control loop for instance 100 assembly codes, it will consume 5 us to complete the execution in 8 MHz oscillator.
