Make a graph from database record and either send it to a printer
directly selecting many print options or copy it in any file on disc.
This project also gives you print preview option for A4 size paper and
you can set your graph anywhere on the page.Also if you want to change
graph s height or width you can change.Zooming effect is also given
using hsrollbar.
Offers sound advice on selecting a thesis or postdoctoral adviser, choosing among research jobs in academia, government laboratories, and industry, preparing for an employment interview, and defining a research program.
Launch Matlab by either clicking twice on the Matlab icon on your desktop or by selecting: Start Programs Matlab Matlab. The main window is the MATLAB Command Window, where you write your instructions.
Normally a list view is updated by a user directly by selecting a list view item and then editing or deleting it. New items are usually added at the bottom of the list. This works fine since the user knows which items have been changed or deleted and where the new items will pop up. A drawback of it is that, if the list is sorted, then new items will not be displayed in a sorted way, instead they will be listed in the order of being created.
Flight panel java GUI selecting the departure city, origin city, the day and time of travel, number of adults and children travelling and will calculate the total order.
設(shè)計了一種基于PIC16C71單片機的數(shù)字水溫配制閥。該配制閥采用NTC熱敏電阻作溫度傳感器,與固定電阻組成簡單分壓電路作為水溫測量電路,利用PIC16C71單片機內(nèi)置的8位A/D轉(zhuǎn)換器把熱敏電阻上的模擬電壓轉(zhuǎn)換為數(shù)字量,PIC16C71單片機控制直流電機驅(qū)動混水閥調(diào)節(jié)冷熱水的混合比例實現(xiàn)水溫調(diào)節(jié)。給出了控制電路圖,對水溫測量電路的參數(shù)選擇和測溫精度作了詳細討論。實驗和分析表明,選用阻值較大的NTC熱敏電阻和分壓電阻可較好地解決熱敏電阻因功耗較大造成的熱擊穿問題。
Abstract:
A digital valve for controlling water temperature based on PIC16C71 was presented in this paper.A bleeder circuit which consisted of a NTC thermistor as temperature sensor and a fixed resistance was designed as water temperature measuring circuit.The analog voltage on the thermistor was converted into digital signal by a 8-bit A/D converter embedded in PIC16C71. Based on the digital signal, the MCU PIC16C71 drived the valve by a DC motor to adjust the water temperature through adjusting the proportion of hot water and cold water.The circuit diagram of controller was given,the principle,the component parameters and the accuracy of measuring temperatures were also dissertated in detail. It was found by experiment and analysis that thermal breakdown of thermistor caused by high power could be solved by selecting thermistor and fixed resistance with high impedance value.

Abstract:
This paper chooses A/D conversion method to realize the keyboard interface of the controller by using ATmega168 microchip from Atmel Company.It accomplishes 30-key dealing sensitively and reliably in massage chair through skillfully selecting resistors in hardware circuit and using digital filter,dichotomy and area-judging method in software design.The hardware design circuit, software design idea and partly assembles code are presented mainly.
The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequences include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric.
Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.
