The potential for tidal stream power in North Western European waters is large and a number of axial flow, vertical rotor and oscillating hydroplane schemes are approaching full scale design and construction. The accurate determination of the available or potential fluid power is being addressed by, in particular, the regulatory bodies as they move towards the establishment of industry standards and the identification and designation of licensing areas. A generic formulation is developed here which utilises Admiralty tidal diamond data and the arithmetic summation of harmonics due to the lunar semi-diurnal, the solar semi-diurnal and (for shallow water and estuarine sites) the lunar quarter diurnal components. Numerical and sensitivity analyses show that the long term potential power is sensitive to the amplitudes of the harmonics but insensitive to the frequencies and phase differences. The results are applied to estuarine sites off Immingham and at Hull Roads in the Humber and to a shallow water, coastal site off Weston-super-Mare in the Bristol Channel. The results indicate that the shore side energy output from a small scale, meso-generation, 100 m2 capture area device with 60% efficiency varies from about 600 MWha–1 in the Bristol Channel to about 900 MWha–1 in the Humber where the ebb dominated tide flows for longer durations and at slightly higher speeds.

Abstract Individual engineering design projects face different challenges depending on their scale. Instead of dealing with problems of complex multidisciplinary systems, small scale design must overcome issues of limited resources. The philosophy of agile software development has been highly successful in addressing similar issues in the software engineering realm over the past two decades. Through the design and prototyping of a low-budget desktop stereolithography printer, the application of agile principles to engineering design process is explored. The printer’s design is discussed in detail to provide examples of successes and failures when these agile principles are put into practice. The paper concludes with a discussion of how agile principles could be leveraged in engineering design. The approach taken in this paper is more of a longitudinal study of a single design process over a twelve-month period as opposed to rigorous experiments that engage multiple users in short design scenarios. Nonetheless, this case study demonstrates how the application of agile principles can inform, improve, and complement traditional engineering design processes.

The small-scale fabrication industry is of great importance to developing an economy. In the last two decades governments and private agencies in Nigeria have demonstrated great concerns in developing the Small Scale Industries through policy formulation and support for agencies created with a view to developing the industry. But such concerns have not yielded any good results. There are therefore some salient problems bedeviling this sector. The work presented in this paper is a study of the constraints to the growth of the small scale fabrication industry in Nigeria using Benin metropolis as a case study. Structured questionnaires were used to collect primary data and interviews were also conducted. The data collected were then analyzed and the constraints to the growth of the industry were identified. The results obtained from the study showed that non awareness of government policies; inadequate technology, inadequate educational training and lack of finance are the major constraints to the development of the small scale design and fabrication industry in Nigeria. Recommendations are made for overcoming these constraints.

Automasi rumah adalah satu cabang teknologi yang sedang giat diperkembangkan disebabkan kemudahan yang diberikan. Alasan untuk memilih suara adalah kerana ia mudah dihasilkan oleh manusia. Selain itu, penggunaan suara memberikan sistem kawalan yang berkesan dan selesa untuk digunakan. Penerapan sistem ini melibatkan pengubahsuaian sistem suis dari cara tradisional yang merupakan sentuhan fizikal dengan beralih ke cara yang lebih selamat di mana penggunaan suara untuk menggantikan semua sentuhan fizikal. Projek ini melibatkan sistem suis mudah yang menggunakan transistor bersama–sama dengan geganti untuk kesemua sambungan kuasa ke peranti, sistem pengecaman suara yang terdiri daripada cip pengecaman suara HM2007, dan mikro pengawal PIC18F8722 untuk membina sistem. HM2007 berfungsi telinga yang akan mendengar dan mentafsir arahan masukan yang diberikan sementara PIC18F8722 berfungsi sebagai otak dari sistem yang akan menyelaraskan keluaran yang betul dengan arahan masukan yang diberikan. Projek ini boleh mengecam arahan yang dilatih oleh pengguna dan berjaya untuk melaksanakan keluaran yang betul. Projek ini merupakan reka tiga bentuk berskala kecil yang terdiri daripada 8 arahan yang digunakan untuk mengendalikan suis yang berbeza. Arahan ini boleh secara individu untuk menghidupkan dan mematikan suis. Selain itu, arahan juga mampu menghidupkan dan mematikan semua suis pada masa yang sama. Kata kunci: Pengecaman suara; sistem rumah automatik Home automation is currently getting widespread recognition due to the convenience it provides. Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, and other systems, to provide improved convenience, comfort, energy efficiency and security. This research is focus on creating a voice recognition system as an aid to home automation. Reason for choosing voice is because it is easily being reproduced by human. Besides that, usage of voice gives a control system that can be effective and convenient to be used. The application of this system involve modifying the switching system from the traditional way which is physical contact with a switch to a safer way where the usage of voice to replace all the physical contact. This project involve a simple switching system that used the transistor along with relay to power the devices, a voice recognition system that consists of voice recognition chip HM2007 and the PIC18F8722 microcontroller. The HM2007 serves as the recognition chip that listens and interpret the command by the given input while the PIC18F8722 serve as the brain of the system that will coordinate the correct output with the input command given. This project able to recognize the command trained by the user and successfully to execute the correct output. This project is a small scale design which consists of 8 commands that used to control three different switches. The command is able to individually switch on and switch off each of the switch. Besides that, the command also able to switch on and off all the switch at the same time. Key words: Voice recognition; home automation system
