This paper presents needle insertion forces for haptic feedback device in soft tissue. The force information from needle insertions is being measured by the sensor. The force feedback produced by the device is used in robot-assisted percutaneous therapies. The objective of the work reported here is to design a device for reality-based data. Insertion force data was collected on chicken skin and meat. The needle insertion force is modeled in three parts; force due to capsule stiffness, friction and cutting. The data from model is compared with real time force data. From the simulation and experimental results, it is found out that the error between measured and modeled force converges to zero.

Reverse osmosis Desalination plants are a widely used application of water treatment engineering all over the world. Therefore devising control systems for these plants is a must in our modern automated industrial world as different systems has been devised yet their technology became obsolete by time. On the other hand complicated and over rated control systems are not convenient to use with these types of plants, especially for remote areas. Therefore, coming up with a monitoring system to monitor and control a Reverse Osmosis water treatment plant is a convenient solution with computer based software. The plant can be monitored using a PC enhanced with industrial automation software like LABVIEW® and a data acquisition card to build up a SCADA system for the water treatment plant. This work illustrates the structure and the installation of a flexible and low cost SCADA system. An ordinary PC with the appropriate interface and software operates the system. The system is installed to a lab scaled water plant which is designed and built. The system has proved the expediency of PC based SCADA systems over the conventional control systems.
反渗透海水淡化装置是世界范围内广泛应用的水处理工程。因此,在我们现代自动化工业世界中,为这些工厂设计控制系统是必须的,因为设计了不同的系统,但它们的技术随着时间的推移而过时。另一方面,复杂和过高额定的控制系统不便于这些类型的工厂使用,特别是在偏远地区。因此,利用计算机软件设计一套监测系统来监测和控制反渗透水处理厂是一种方便的解决方案。可以使用带有工业自动化软件(如LABVIEW®)和数据采集卡的PC机对工厂进行监控,以建立水处理厂的SCADA系统。本文阐述了一种灵活、低成本的SCADA系统的结构和安装。一个普通的个人电脑与适当的接口和软件操作系统。该系统安装在已设计和建造的实验室规模的水厂上。该系统证明了基于PC机的SCADA系统相对于传统控制系统的方便性。

The main focus of this research is to analyze EEG signal of smokers after undergoing Horizontal Rotation (HR) treatment. 21 male smokers were sampled in this study. EEG data was captured before and after HR for 5 sessions. In addition, some demographic data were gathered from the samples to check their smoking habits. It was found that, HR significantly improves the Alpha band that could reduce the smoking habit.

Miniaturized microstrip ring filter is presented. Four lumped capacitors are added in the initial ring resonator topology to shift the resonant frequency to about 50% of its nominal value, leading to size reduction of the filter. The required value of the capacitors is calculated using tuning synthesis equations of the ring resonator. The passband response of the filter is improved by modifying the line impedance of the ring. The final layout of the miniaturized filter centered at 2.76 GHz is compared to its counterpart showing a size reduction of about 67%.

This paper discussed on photoresist etching characterization in 5 % KOH etchant. The work that has been done at UTHM clean room, consists of three main experiment parameters which are bake time, spin speed, and UV expose time. The mask pattern used in this work is based on microneedle array masking design. The observations were done in term of, photoresist thickness and percentage photoresist remaining after wet etching process. The positive resist, PR-2000 was used for the work and grid approximation based on high resolution imaging microscope was used as statistical technique to characterize the effect. The obtained etching behaviors on every microneedle masking array will be useful to assist in developing recipes to fabricate microneedle microstructure.

Aspect Oriented Software Development (AOSD) provides efficient solution for modularity and handling of crosscutting concerns. Recent research proposes use of AOSD in SPL for better separation of concerns and modularity to increase variability that leads to more reusable core assets. This paper highlights the gap in the area of reusability assessment of aspect oriented product line core assets and proposes a reusability assessment framework for aspect oriented product line core assets.

This paper presents the design of a reconfigurable low noise amplifier (LNA) for multi-standard multi-band receiver. In this design, inductively-degenerated common-source (IDCS) topology is chosen as it has been proven to be a good choice in designing multi-standard multi-band LNA. The design is using 0.18 μm CMOS technology. The reconfigurable LNA has been designed to operate in two bands of standards consisting the bands range from 800 to 1000-MHz (lower band) and 1800 to 2200-MHz (upper band). The simulation results exhibit gain S21 of 12.9-dB for lower band and 12.4-dB for upper band, input reflection S11 of −14.5-dB and −17.2-dB for both bands, and output return loss S22 of −14.7-dB and −26-dB for lower and upper band making the LNA suitable for most of the mobile communication applications. The LNA also exhibits the noise of figure of 2.55-dB and 2.3-dB for lower and upper band respectively. The circuit consumes 26.5 mW when operating in lower band mode and uses 18.8 mW of power when operating in upper band mode.

Feeders form a critical part of automated assembly lines. Along with feeding from a bulk supply, they also convert the randomness of parts into a flow in a geometrical pattern and deliver them at a predetermined rate. This paper mathematically analyses a reciprocating-fork hopper feeder. This system supplies headed parts like bolts and rivets in an upright configuration to the delivery chute through a pneumatically-actuated reciprocating fork which picks up the parts from a rotating bowl. The feed rate performance of the feeder is analysed for three parameters: part population, rate of reciprocation of fork and speed of rotation of bowl. The Design of Experiments (DOE) is done using 23 full-factorial method. A mathematical model is formulated using Design Expert ® software, to investigate the significance of individual parameters as well as interactions amongst them. Adequacy of the model to predict the performance of the feeder is checked using Analysis of Variance (ANOVA) method. The results obtained are presented graphically and in the form of factorial model which defines the performance characteristics of the feeder. The mathematical model also provides the most appropriate process parameter settings to optimize the feed rate of the feeder under the given constraints.

This paper describes the specification of interaction protocol for automating the document downloading and notification in the e-learning by adopting the Electronic Institution (El) infrastructure. This interaction protocol is designed using specific tool called ISLANDER editor which is one of the Electronic Institution Integrated Development Environment (EIDE) components. The idea of designing this interaction protocol is believed can eliminate the tendency of students from missing out the latest updates available in their e-learning. Furthermore, with the adoption of agent-based environment for e-learning will add a new feature to the existing e-learning in a way of assisting a busy lifestyle of students to hand over the task of downloading lecture materials and checking the latest announcements available in the e-learning to the software agent straight to their desktop. Hence, the students will not miss any important announcements or latest learning materials uploaded by their lecturers. In this paper, we are only focusing and describing the process of specifying interaction protocol using ISLANDER editor.
本文描述了采用电子机构(Electronic Institution, El)架构实现电子学习中文档下载和通知自动化的交互协议规范。该交互协议是使用名为ISLANDER编辑器的特定工具设计的,ISLANDER编辑器是电子机构集成开发环境(EIDE)组件之一。设计这种交互协议的想法被认为可以消除学生在他们的电子学习中错过最新更新的趋势。此外,采用基于代理的电子学习环境将为现有的电子学习增加一个新功能,帮助学生在繁忙的生活方式中将下载课程资料和查看电子学习中可用的最新公告的任务直接交给软件代理到他们的桌面。因此,学生不会错过任何重要的公告或最新的学习资料上传到他们的讲师。在本文中,我们只关注和描述了使用ISLANDER编辑器指定交互协议的过程。
