The Uses Of Computers In Property Management & Valuation
No full textPerkembangan penggunaan komputer di dalam bidang Pengurusan Hartabenda dan Penilaian adalah tidak begitu menggalakkan. Kertas ini membincangkan sebab mengapa kemajuannya terhad dan bagaimana pergolakan terbaru di dalam teknologi komputer telah akhirnya dapat membawakan kebaikan penggunaan komputer kepada firma-firma yang bersangkutan dengan pengurusan, pembangunan dan penilaian hartanah. Bahagian kedua kertas ini membincangkan tugas-tugas yang boleh dilaksanakan dengan cukup memuaskan oleh sesebuah komputer;
1. Menyimpan dan mendapat balik data
2. Memilih, mengguna dan menganalisa data
3. Mengerjakan pengiraan yang rumit dan/atau yang berulang
4. Memproses perkataan
Setiap tugas-tugas ini adalah bersangkutan dengan bidang amalan ikhtisas yang mana akan mendapat menafaat dengan penggunaan komputer. Akhirnya, kertas ini membincangkan faedah-faedah yang boleh dinikmati oleh bidang ikhtisas ini sekiranya teknik-teknik komputer
digabungkan di dalam amalan praktik.
The development of computer application in the areas of Property Management and Valuation has been relatively slow. This paper discusses the reasons why progress has been limited and how the recent revolution in computer technology has finally brought the many advantages of computerisation into the reach of most firms dealing with the management, development and valuation of landed property.
The second half of the paper considers the tasks which the computer is able to perform exceptionally well,
1. storage and retrieval of data
2. sorting, manipulating and analysis ofdata
3. performing complex and/or repetitive calculations
4. word processing
Each of these tasks is related to areas of professional practice which could benefit from computer application. Finally, the paper discusses the benefit which may be enjoyed by the profession if computer techniques are incorporated into practice
Tunnel Liner Subjected To Excavation Loading
No full textSatu kajian makmal telah dibuat untuk menganggar momen-momen, daya-daya tujah dan cangga\u27an dalam suatu dinding terowong yang dikenakan \u27beban korekan\u27. Kesan-kesan kedalaman timbusan ke atas daya tujah, mimen dan cangga\u27an telah dikaji dan keputusan-keputusan dibandingkan dengan penyelesaian-penyelesaian yang dikemukakan oleh Burns dan Richards (1964) dan oleh Morgan (1961)
dan penyelesaian secara \u27finite element\u27 oleh Mohraz dll. (1975). Penyelidik menyatakan bahawa adanya persetujuan diantara nilai-nilai beban dari ujikaji dengan perhitongan kemukaan Morgan (1961) adalah baik dan cadangan kedua boleh digunakan untuk merekabentuk dinding-dinding terowong yang tertimbus dengan dalamnya dan dikenakan oleh beban korekan. Dalam masalah timbusan cetek, bagaimanapun, agakan untuk daya tujah, momen dan cangga\u27an boleh dikira dengan menggunakan persamaan-persamaan untuk dinding tegar.
A laboratory study is conducted to estimate moments, thrusts and deformation in a tunnel liner subjected to \u27excavation loading\u27. The effects of thrust, moment and deformation of the depth of burial are examined and the results are compared with the solutions offered by Burns and Richard (1964) and by Morgan (1961) and the finite element solutions of Mohraz et al. (1975). The researcher concludes that the agreement between the experimentally determined load values and those calculated from Morgan (1961) is so good that the latter are applicable to the design of tunnel liners to be deeply buried and subjected to excavation loading. In problems of shallow cover, however, reliable estimates of thrust, moment and deflection can be obtained by using rigid liner equations
Use Of Direct Solar Energy In Torrid Zone
No full textMatahari ialah punca tenaga yang utama kepada keluarga planetnya. Ia memancarkan tenaga dalam bentuk gelombang elektromagnet, yang merambut melalui ruang udarakasa dengan halaju 299,744 km (186,270 batu) sesaat. Planet bumi melintasi sepecahan
tenaga ini di dalam bentuk haba dan cahaya. Dengan ini ujudlah ke atas bumi, keadaan-keadaan asas bagi suhu dll yang mengakibatkan jiwa boleh jadi. Tenaga matahari yang bercahaya membekalkan tenaga kepada keseluruhan kitar kajihayat jiwa melalui cara fotosintisis. Matahari, melalui sebaran tenaga yang tidak sama atas planet bumi, ialah punca utama, yang menghasilkan peredaran udara, aliran laut, pengangkutan air melalui proses cairwapan dan kerpasan sebagai hujan atau salji dan pengaliran melalui sungai. Pemerhatian-pemerhatian mengusulkan bahawa kekuatan fizikal manusia, kebolehan rohani, keperluan tenaganya, konsep keenakan dll semuanya bergantung kepada berapa banyaknya pengdedahan kepada pancaran matahari. Oleh sebab itu, untuk memahami cara menahan jiwa, dan mengguna dengan sepenuhnya alam sekitar yang lazim serta menghasilkan keadaan-keadaan optimum bagi kehidupan dan pekerjaan, adalah sangat penting untuk memahami perhubungan antara manusia dan matahari. Kefahaman ini boleh menolong manusia memenuhi keperluan untuk tenaga, keperluan bagi kehidupan keenakan tanpa bergantung kepada teknologi yang mahal. Kertas kerja ini berbahaskan perhubungan antara manusia dan alam sekitarnya yang lazim, khasnya dengan matahari.
The sun is the main source of energy to its family of planets.It radiates energy in the form of electromagnetic waves, which are propagating through space with a velocity of 299,774 km (186,270 miles) per second, The planet earth intercepts a fraction of this
energy in the form of heat and light, that creates on the earth, the basic conditions of temperature etc. which make life possible. It is the radiant solar energy, through the mechanism of photosynthesis that provides energy for the whole biological cycle of life. The sun, through its unequal distribution of energy on the planet earth, is the prime source, that is producing circulation of atmosphere, oceanic currents, transport of water through the process of evaporation and precipitation as rain or snow and flow through streams and rivers. Observations suggest that man\u27s physical strength, mental capabilities, his energy requirements, concept of comfort etc. all depend on the extent of his exposure to the solar radiation. Therefore, in order to understand the life sustaining mechanism, utilize the best of natural environments and create optimum conditions for living and working; it is all the more important to understand man\u27s relation with the sun. This understanding can assist him to fulfill
his needs for energy and comfortable living without much dependence on expensive technology. The paper discusses man\u27s relationship with his natural environments, especially with the sun
Some Aspects of Combustion and Heat Release in Diesel Engines
No full textThe author discusses the various stages of combustion in diesel engines from experiments conducted by himself and also by various other research workers in this field.
He then outlines the technique used in predicting heat released by the fuel during combustion in a diesel engine - a techniq ue on which he has worked during his Master\u27s course at the University of Manchester Institute of Science and Technology.
The technique consists of applying the first Law of Thermodynamics in steps of the period from inlet valve closure to exhaust valve opening. The First Law equation applicable is reformulated so as to be used on the digital computer
Effect of Axial Compressibility on the Snap-Through Buckling of Prestressed Arches
No full textA generalized theory is used to investigate the effect of axial compressibility on the stability of a prestressed arch obtained by buckling a strut into a deformed shape and then attaching it to its supports. For various amounts of compressibility, geometric and mechanical quantities caused by a uniform load that produces large displacement are computed. Symmetric and, in some cases, unsymmetric modes of buckling are found
Ellipsoidal Separation: A Medical Diagnostic Systems Technique
No full textA technique for separating clustered date through the use of n-dimensional ellipsoids surrounding the clusters is discussed. The ellipsoids are minimal in the sense that a maximum number of data points lie on their boundaries. The theory is set up for the computer aided classification of patients according to the presence or absence of a disease, though it is applica ble to other similar situations
Digital Simulation of Saturated Electro-mechanical Energy Converters
No full textBased on th e now familiar Bond Graph analysis the process of electromechanical energy conversion in electrical machines is studied in detail. The paper avoids the use of transformation matrices and relies on the diagramatic representations which evolve from the bond graph method to extract the necessary mathematical equations for subsequent digital simulation
