Study of Wetting Phenomenon During Cooling of Curved Surfaces Using Impinging Water Jets
No full textTitle: Study of Wetting Phenomenon During Cooling of Curved Surfaces Using Impinging Water Jets, Author: Muhammad Akmal, Location: ThodeWetting phenomenon during cooling of hot cylindrical specimens using Impinging Jet
of water has been studied. Effect of jet velocity, jet diameter, water temperature,
specimen surface temperature and surface curvature on propagation of wetting front has
been analyzed. Propagation of wetting front correlated well with power function of time.
Experiments were conducted at specimen surface temperatures of 250, 500 and 800°C.
Water temperatures of 20, 50 and 70 or 75 or 80°C were employed with Jet velocities of
5 and 7.75m/sec. Jet diameters of 3mm and 4mm were utilized during experiments.
Propagation of wetting front strongly depends upon water temperature. Wetting front
grows faster at low water temperature and high jet velocities. For constant water
temperature, growth of wetting front is high with high jet velocities. Velocity of wetting
front increases with jet diameter of 4mm when compared with that of 3mm due to
increase in mass flow. The influence of jet diameter is greater for low water temperature,
low surface temperature and high jet velocities. Effect of jet velocity and degree of subcooling
on constant "a" and exponent "n" of the power relation are studied. Constant "a"
is found to be linear function of jet velocity and degree of sub-cooling. Exponent "n"
appears to be independent of jet velocity but weekly dependent on degree of sub-cooling. Propagation of wetting front with time was analyzed in comparison with the
transient temperature drop of material for different thermocouples embedded at stream
wise locations within specimen at a distance of 1mm from surface. Temperature readings
were used to predict the propagation of wetting front, which was found to be valid for a
distance of 10mm from impingement point. Effect of surface curvature was analyzed by comparing the results of present
study with those reported by previous researchers. Surface curvature was found to have
significant impact on propagation of wetting front.ThesisMaster of Applied Science (MASc
Administration of estates in Malaysia: Law and procedure. By Akmal Hidayah Halim. Selangor, Malaysia: Sweet Maxwell & Asia, 2012, pp. 221. ISBN: 9789675040849
No full textAkmal Hidayah Halim, the author of the volume under review, has earlier published The Law of Wills and Intestacy in Malaysia (Selangor, Malaysia: International Islamic University Malaysia, 2009). Administration of Estates in Malaysia is based on the author’s Ph.D. thesis. The subject matter of this book is extremely important in the legal fraternity as it deals with property left by the deceased. There are many cases in Malaysia where the money and property left by the deceased has gone unclaimed either because the members of general public were unaware of the procedure to follow in claiming the estates or because the deceased failed to name the legal administrator of the estate upon his/her death

Temperature based fan speed control
No full textTable fan are one of the most commonly used equipment in the Malaysia. The innovation and the improvement of the table fan in term of the power consumption of electricity will give a huge impact on the table fan market value. Almost every household in Malaysia have a table fan, this shows how much Malaysian need fan in this region. Malaysia’s climates are hot and humid all year around. Therefore, table fan plays a huge role on cooling down the citizens in their house. Though the table fan marketing in Malaysia is good, the problem arose when people tend to forget or intentionally let the table fan turn on when they do not use it or when the temperature is decreasing. Some, Malaysian also use fan when the weather is not really hot and some use the fan table even when they turn on the air conditioner. With the help of technological advancement, these problems can be tackled head on with the use of a temperature sensor. The sensor will detect the surrounding temperature and a microcontroller will be used as a brain which will receive the temperature from the sensor and will gives out a suitable command to the table fan according to the surrounding temperature
Investigation of zero crossing detection for first return stroke in negative cloud-to -ground lightning flash
No full textThis paper aims to investigate the minimum threshold for zero crossing detection of the first return stroke in negative cloud-to-ground lightning flashes. The uncertainty for a minimum threshold to be set into a programmed software for an automatic zero crossing detection motivated the author to overcome the problem. The software was built-in MATLAB. The development of the software considered the important parameter of lightning strike from the preliminary breakdown stages until the first return strokes. A single station measurement was setup in Ayer Keroh, Malacca. 41 samples of duration of the zero crossing time were recorded by using Lecoy HDO4024 with 5 MS/s. The results showed that the minimum threshold for zero crossing detection was 40µs with 82.9% accuracy. In conclusion, the minimum threshold of zero crossing detection of the first return stroke in negative cloud-to-ground was determine
Analisis Percepatan Pekerjaan Pipeline Pada Tahap Perencanaan Proyek Wellhead Platform PT. X Menggunakan Metode Time Cost Trade Off
No full textPada proses perencanaan proyek wellhead platform terdapat banyak aktivitas / pekerjaan yang dapat memakan biaya yang sangat besar jika tidak dikelola dengan baik. Karena terdapat hal - hal yang dapat terjadi ketika pengelolaan proyek tidak dilakukan dengan baik, contohnya adalah terjadinya keterlambatan pada aktivitas / pekerjaan proyek yang menyebabkan keterlambatan pada keseluruhan durasi proyek. Maka dari itu penulis melakukan penelitian untuk mencegah keterlambatan dengan melakukan analisis percepatan pada proyek perencanaan wellhead platform dengan menggunakan metode time cost trade off dan dilakukan analisis probabilistik dengan melakukan simulasi monte carlo untuk mendapatkan durasi yang paling memungkinkan untuk proyek dapat diselesaikan. Pada penelitian ini penulis menggunakan 2 alternatif percepatan yaitu Alternatif I penambahan jam kerja 1 jam dan Alternatif II penambahan jam kerja 2 jam. Dari penelitian ini ditemukan bahwa dengan menggunakan Alternatif I yaitu menambahkan jam kerja 1 jam maka durasi yang paling mungkin dapat terjadi berkurang sebanyak 3 hari menjadi 124 hari dengan kenaikan total biaya sebesar Rp 64,702,410 atau sebanyak 6.37% menjadi Rp 1,080,676,616. Sedangkan pada Alternatif II yaitu menambahkan jam kerja 2 jam kerja didapatkan bahwa durasi yang paling mungkin dapat terjadi berkurang 7 hari menjadi 121 hari dengan kenaikan total biaya sebesar Rp 88,218,092 atau sebanyak 8.68% menjadi Rp 1,104,192,299.

In the process of planning a wellhead platform project, there are many activities/tasks that can incur significant costs if not managed properly. Due to the potential issues that can arise when project management is not carried out effectively, such as delays in project activities/tasks leading to overall project duration delays, the author conducted research to prevent delays by performing acceleration analysis on the wellhead platform planning project using the time-cost trade-off method. Additionally, probabilistic analysis was conducted by performing Monte Carlo simulations to obtain the most probable duration for the project to be completed. In this research, the author utilized two acceleration alternatives: Alternative I, involving the addition of 1 working hour, and Alternative II, involving the addition of 2 working hours. From the study, it was found that by using Alternative I, which adds 1 working hour, the most likely duration that can occur is reduced by 3 days to 124 days, with a total cost increase of Rp 64,702,410 or 6.37%, amounting to Rp 1,080,676,616. On the other hand, Alternative II, which adds 2 working hours, resulted in a reduction of 7 days in the most probable duration to 121 days, with a total cost increase of Rp 88,218,092 or 8.68%, amounting to Rp 1,104,192,299

No full textThe Cureh Main Market is the main market in Bireun Regency which is the center of the sub-district markets that operate from morning to evening and even late at night, but this does not happen in the Cureh Main Market, as is the phenomenon that has occurred until now people prefer shopping at the Meunasah Capa Morning Market, namely markets around settlements near people\u27s homes as well as modern markets or online ordering, if this problem is not handled quickly, the Cureh Main market cannot last long in Bireun district. This study uses a qualitative method, in which qualitative data analysis is carried out interactively and is carried out continuously until it is complete, so that the data is saturated. The research results obtained are: 1. Cureh Main Market Arrangement and Maintenance Policy Reviewing the Market Management Administration System using three elements of content of policy from Grindle\u27s theory. 2. Obstacles that occur so that the Cureh Main Market is not yet functioning optimally are reviewed with internal and external constraints, namely a. Internal constraints are caused by factors related to strategic locations in selling as well as the importance of knowledge and skills, as well as market conditions that greatly affect customers with muddy market conditions and flooded roads making the location look dirty and garbage scattered following the puddles which makes customers reluctant to go to the market during the rainy season. b. External constraints are caused by factors that there is no solution to avoid conflicts, as well as the rapid competition that is currently emerging with many people shopping and ordering food and vegetables, which can now be ordered using an online application. The suggestion that the author hopes is that the government and all traders work together and can continuously maximize the strategy for structuring and maintaining the Bireuen Regency Main Market, both administratively and revitalizing the construction of facilities and infrastructure of the Bireuen Regency Main Marke
