Limiters for DEMO wall protection: Initial design concepts & technology options

With the introduction of field-emission sources and “immersion-type” objective lenses, the resolution obtainable with modern scanning electron microscopes is approaching that obtainable in STEM and TEM-but only with specific types of specimens. Bulk specimens still suffer from the restrictions imposed by internal scattering and the need to be conducting. Advances in coating techniques have largely overcome these problems but for a sizeable body of specimens, the restrictions imposed by coating are unacceptable.For such specimens, low voltage operation, with its low beam penetration and freedom from charging artifacts, is the method of choice.Unfortunately the technical dificulties in producing an electron beam sufficiently small and of sufficient intensity are considerably greater at low beam energies — so much so that a radical reevaluation of convential design concepts is needed.The probe diameter is usually given by

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.

Abstract: A house is a basic need for every human’s life. It is not only a place for shelter, but also a place for a family to live, to have social interaction between them, to raise the children, and to give the values of life. Padma Residence is a modern residence which is built by PT. Surya Coco Jaya. Most of its residents make changes to their houses after they occupy it. The main purpose of this study is to observe changes toward the initial design by comparing the initial design and present condition, recording the present condition of the house when it has occupied by determine architectural elements which are changed, determining causal factors of changes, and finding out dominant causal factors toward alteration of architectural elements of the house at Padma Residence, Bantul, Yogyakarta while it is occupied. Methods used in data collecting are literature study and a field survey. A field survey includes observation, interview, and distributing questionnaires to 25 respondents who are the owners of houses in this residence. Data analysis used table which compare the initial design and nowadays condition. The result of data processing and analyzing reveals that the owners do physical changes at their houses while they occupy them, particularly at the front appearance of the house. The changes include the addition of canopies at carport and changes in the layout of the rooms, such as kitchen, dining room, and backyard. A dominant factor which has caused those changes is the function of rooms which is added to the house.Keywords: residence, physical changes, the additon of functionAbstrak : Rumah merupakan kebutuhan utama bagi kehidupan setiap manusia. Selain sebagai tempat untuk berlindung, rumah juga merupakan wadah atau tempat manusia atau sebuah keluarga melangsungkan kehidupannya. Perumahan Padma Residence merupakan sebuah hunian modern yang dibangun PT. Surya Coco Jaya dan sebagian besar penghuninya melakukan perubahan pada rumah tinggalnya saat ditempati. Tujuan utama penelitian ini adalah mengetahui perubahan terhadap desain awal rumah tinggal dan kondisi rumah tinggal tersebut saat ditempati dengan mengetahui unsur-unsur arsitektural yang berubah pada desain rumah tinggal saat ditempati di Perumahan Padma Residence, Bantul, Yogyakarta. Metode penelitian dilakukan dengan studi literatur dan survei lapangan. Survei lapangan meliputi pengamatan, wawancara, dan penyebaran kuesioner kepada 25 responden yang merupakan pemilik rumah tinggal di perumahan tersebut. Hasil dari pengolahan dan analisis data menunjukkan bahwa pemilik rumah melakukan perubahan fisik pada rumah tinggalnya saat ditempati, terutama pada tampilan depan bangunan, perubahan yang dilakukan adalah menambahkan kanopi pada carport, peletakan ruang seperti dapur, ruang makan, dan taman belakang. Faktor-faktor yang menjadi penyebab perubahan tersebut adalah pertambahan fungsi ruang.Kata kunci: rumah tinggal, perubahan fisik, pertambahan fungsi

Reinforcement Material

Aluminium based composites exhibit many attractive material properties such as increased stiffness, wear resistance, specific strength and vibration damping and decreased co-efficient of thermal expansion compared with the conventional aluminium alloys. Aluminium Matrix Composites consist of non-metallic reinforcement which offers advantageous properties over base material. Reinforcements like SiC, B4C and Al2O3 are normally preferred to improve the mechanical properties. Here Aluminum LM25 is selected as matrix material while Silicon carbide and Boron carbide are selected as reinforcement material. The fabrication of aluminium matrix was done by stir casting method. In the present study an attempt has been made to investigate the effect of three major stir casting parameters (stir speed, stir duration and preheated temperature of reinforcement material) on stir casting of Aluminium LM25 - SiC - B4C composite. Experiments were conducted based on Taguchi methodology. Taguchi quality design concepts of L9 orthogonal array has been used to determine S/N ratio and through S/N ratio a set of optimum stir casting parameters were obtained. The experimental results confirmed the validity of Taguchi method for enhancing tensile strength of castings.

Design Proposal

One-solving methods and techniques necessary to avoid inefficiencies and not economic costs as well as reduce the cost of housing construction is the method of Value Engineering. Value engineering is a method and cost control techniques to analyze a function to its value at the lowest cost alternative (most economical) without reducing the quality desired.At the writing of this study used a comparison method by comparing the initial design to the design proposal of the author. In the housing projects Upgrading Tirto Penataran Asri type 70, the application of Value Engineering conducted on the job a couple walls and roofs pair by replacing some work items with a more economical alternative but does not change the original function and high aesthetic level and still qualify safe. For that performed the step of determining a work item, the alternative stage, the analysis stage, and the stage of recommendations to get a Value Engineering application and cost savings against the wall a couple of work items and partner roof.The proposed design as compared to the initial design. Work items discussed was the work of a couple wall having analyzed obtained savings of Rp. 2,747,643.56 and the work of the roof pair obtained savings of Rp. 2,363,446.80. Thus the total overall savings gained is Rp 5,111,090.36 or savings of 0048%.
