User-friendly universal control unit

Precision agriculture is a farming system based on the combination of detailed observations, measuring and rapid-response to optimize energetic input to maximize crops production. Precision agriculture use decision support system (DSS) for optimize farm management. In this context, EVJA Observe Prevent Improve (or just EVJA) is an Intelligent Support System for precision agriculture. A vast set of data (i.e. temperature, relative humidity, deficit of vapour pressure, leaf wetness, solar radiation, carbon dioxide concentration, soil moisture etc.) is continuously collected, submitted to a local control unit, and processed through algorithms specifically developed for different crops. On the other hands, farmers can access EVJA from their pc and mobile devices, and monitor complex agronomic data analysis presented in a user-friendly interface.In this article, we will show how EVJA works, and how its output can be used to assess the health state of plants through a specific set of functions. Moreover, we will show the methodology to develop useful predictive models based on this information.Specifically, we will describe a predictive algorithms capable to predict the infection risks of downy mildew for baby leaves plantations and for Fusarium ear blight of wheat.

Implementation of home automation using the latest technology gives us more convenience, security and safety. Smartphone affordability increases every year and smartphones have begun to play important roles in our daily lives due to their size and portability. Google’s Android operating system (OS) is one of the leading and most preferred smartphones. Controlling home appliances by using an Android phone gives users the ability to control their home appliances anywhere and at any time while at home and saves time spent in searching for the remote control unit of home automation systems since the user’s phone is usually kept close at hand. This project presents the design and implementation of a low cost prototype of a Bluetooth-based home automation system using an Android phone. The design uses an Arduino Mega 2560-R3 board and the home appliances are physically connected to input/output ports of this board via relays. Cytron BlueBee is used to establish wireless communication between them. BluetoothHome, an Android application, is developed to provide a user friendly graphical user interface (GUI) for the remote control of home appliances.

Nowadays, micro-programming of machines becomes more common. It is a technique used in several fields such as Computer Engineering. Here it is worth mentioning that micro-programming is employed throughout the design process. As well, designing the control unit of digital computers needs micro-programming, which is more complex than assembly languages. In this field, micro-programs can be written as sequences of micro-instructions. In this context, distinguished teaching of micro-programming of machines requires a suitable and carefully chosen Computer Simulation Tool (CST). This research designs a computer hardware project that introduces a special simulator achieving an easy-to-use microprogramming environment and a user-friendly simulation tool. This tool presents a visualization environment in order to display the execution behaviour of microprograms. It is a model/tool designed as a java program to ensure platform independence. This paper presents the Minimax simulator, which is used in the Minimax project. This project is a part of a hardware practical course. Therefore, it is a simulator for microprogramming and hardware simulation. As a result, this simulator facilitates the process of micro-programming significantly enabling students to understand easily how a computer works. Here, two formal measures and metrics were presented to assess the implemented program, the execution time and the program length. Other results of this study showed how self-organized group work and project management can be accomplished.

Various methods of video-enhanced microscopy combine TV cameras with light microscopes creating images with improved resolution, contrast and visibility of fine detail, which can be recorded rapidly and relatively inexpensively. The AVEC (Allen Video-enhanced Contrast) method avoids polarizing rectifiers, since the microscope is operated at retardations of λ/9- λ/4, where no anomaly is seen in the Airy diffraction pattern. The iris diaphram is opened fully to match the numerical aperture of the condenser to that of the objective. Under these conditions, no image can be realized either by eye or photographically. Yet the image becomes visible using the Hamamatsu C-1000-01 binary camera, if the camera control unit is equipped with variable gain control and an offset knob (which sets a clamp voltage of a D.C. restoration circuit). The theoretical basis for these improvements has been described.

Recent progress in computer technology enables the calculation of lens fields and focal properties on commonly available computers such as IBM ATs. If we add to this the use of graphics, we greatly increase the applicability of design programs for electron lenses. Most programs for field computation are based on the finite element method (FEM). They are written in Fortran 77, so that they are easily transferred from PCs to larger machines.The design process has recently been made significantly more user friendly by adding input programs written in Turbo Pascal, which allows a flexible implementation of computer graphics. The input programs have not only menu driven input and modification of numerical data, but also graphics editing of the data. The input programs create files which are subsequently read by the Fortran programs. From the main menu of our magnetic lens design program, further options are chosen by using function keys or numbers. Some options (lens initialization and setting, fine mesh, current densities, etc.) open other menus where computation parameters can be set or numerical data can be entered with the help of a simple line editor. The "draw lens" option enables graphical editing of the mesh - see fig. I. The geometry of the electron lens is specified in terms of coordinates and indices of a coarse quadrilateral mesh. In this mesh, the fine mesh with smoothly changing step size is calculated by an automeshing procedure. The options shown in fig. 1 allow modification of the number of coarse mesh lines, change of coordinates of mesh points or lines, and specification of lens parts. Interactive and graphical modification of the fine mesh can be called from the fine mesh menu. Finally, the lens computation can be called. Our FEM program allows up to 8000 mesh points on an AT computer. Another menu allows the display of computed results stored in output files and graphical display of axial flux density, flux density in magnetic parts, and the flux lines in magnetic lenses - see fig. 2. A series of several lens excitations with user specified or default magnetization curves can be calculated and displayed in one session.

Abstract Using the iPad tablet for Augmentative and Alternative Communication (AAC) purposes can facilitate many communicative needs, is cost-effective, and is socially acceptable. Many individuals with communication difficulties can use iPad applications (apps) to augment communication, provide an alternative form of communication, or target receptive and expressive language goals. In this paper, we will review a collection of iPad apps that can be used to address a variety of receptive and expressive communication needs. Based on recommendations from Gosnell, Costello, and Shane (2011), we describe the features of 21 apps that can serve as a reference guide for speech-language pathologists. We systematically identified 21 apps that use symbols only, symbols and text-to-speech, and text-to-speech only. We provide descriptions of the purpose of each app, along with the following feature descriptions: speech settings, representation, display, feedback features, rate enhancement, access, motor competencies, and cost. In this review, we describe these apps and how individuals with complex communication needs can use them for a variety of communication purposes and to target a variety of treatment goals. We present information in a user-friendly table format that clinicians can use as a reference guide.
