Description: On the Energy Detection of Unknown Signals Over Fading ChannelsAbstract—This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-form expressions for the probability of detection to those recently reported in the literature. Detection capability is boosted by implementing both square-law combining and square-law selection diversity schemes. Index Terms—Diversity schemes, energy detection, fading channels, low-power applications, square-law detector, unknown signal detection.

Description: Example: Distributed Wireless Control System，可用于无线传感器网络中-This example shows distributed control of a DC-servo using
communication over a wireless network. The example also shows how to
simulate power consumption and how to use the battery block. The model
contains two computer nodes located 20 m apart, each represented by a
TrueTime kernel block. A time-driven sensor/actuator node samples the
process periodically and sends the samples over the network to the
controller node. The control task in this node calculates the control
signal and sends the result back to the sensor/actuator node, where it
is actuated. The wireless communication link is at the same time
subject to a simple power control scheme. Power control tasks running
in both the sensor/actuator node and in the controller node
periodically send out ping messages to the other node to test the
channel transmission. If a reply is received, the channel is assumed
to be good and the transmission power is lowered. If on the other hand
no reply is received, then the transmi

Description: Managing Humans is a selection of the best essays from Michael Lopps web site, Rands In Repose. Drawing on Lopp s management experiences at Apple, Netscape, Symantec, and Borland, this book is full of stories based on companies in the Silicon Valley where people have been known to yell at each other. It is a place full of dysfunctional bright people who are in an incredible hurry to find the next big thing so they can strike it rich and then do it all over again. Among these people are managers, a strange breed of people who through a mystical organizational ritual have been given power over your future and your bank account. Whether you re an aspiring manager, a current manager, or just wondering what the heck a manager does all day, there is a story in this book that will speak to you. You will learn:
* What to do when people start yelling at each other
* How to perform a diving save when the best engineer insists on resigning
* How to say "No" to the person who signs your paycheck-Managing Humans is a selection of the best essays from Michael Lopps web site, Rands In Repose.

Description: 很好的OFDM的基于MATLAB的仿真程序包，且包含了最终结果图.-montecarlo
type montecarlo in the command window and wait for a long time..
_simulation of the complete OFDM system.
_use of a very large file in order to get probabilities.
_loop over different value of the noise.
_compute the SNR for each value of the noise.
_provide the SNR/BER plot.
if you are in a rush : simulation_system !!
go into the right folder and type simulation_system in the command window.
_then type the value of the noise power (range = [-20,10])
_the function provides the channel estimation, the bit allocation,
and a plot illustrating the errors.
_this is a fast function (less pilot, no synchronization, small file).

Description: —One of themajor challenges in supportingmultimedia
services over Internet protocol (IP)-based code-division mul-
tiple-access (CDMA) wireless networks is the quality-of-service
(QoS) provisioning with effi cient resource utilization. Compared
with the circuit-switched voice service in the second-generation
CDMA systems (i.e., IS-95), heterogeneous multimedia applica-
tions in future IP-based CDMA networks require more complex
QoS provisioning and more sophisticated management of the
scarce radio resources. This paper provides an overview of the
CDMA-related QoS provisioning techniques in the avenues of
packet scheduling, power allocation, and network coordination,
summarizes state-of-the-art research results, and identifi es further
research issues.

Description: 许多有用的地理位置，太阳能为动力的水泵是特别有利的偏远地区，那里可能没有常规电源提供地下水。令人印象深刻的CY8C27443微控制器为基础的太阳能水泵控制器采用了混合信号阵列，可控制的三阶段电机驱动经营潜水水泵直接从太阳能电池板。
强大的PSoC微控制器提供了三相PWM生成，信号调理，过电流和短路保护，温度监测，并不断的电压频率控制。此外，微控制器CY8C27443最大的电力来自太阳能电池阵列。这样做的结果是强大的，低成本，高效率的控制器。-Solar Pump Controller
Useful in many geographic locations, solar-powered pumps are particularly advantageous in remote areas, where there may not be conventional power to provide ground water. The impressive CY8C27443 microcontroller-based Solar Pump Controller features a mixed-signal array that controls a three-phase motor drive to operate a submersible water pump directly from solar panels. The powerful PSoC microcontroller provides three-phase PWM generation, signal conditioning, over-current and fault protection, temperature monitoring, and constant voltage-to-frequency control. Additionally, the CY8C27443 MCU maximizes the power from the solar array. The result is a robust, low-cost, highly efficient controller.

Description: Very Low Frequency (VLF) spectrograms show
sometimes sets of lines called MLR (Magnetospheric Line
Radiation) with frequency spacing close to 50 or 60 Hz. It is
very tempting to attribute these MLR to Power Line
Harmonic Radiation (PLHR). PLHR are the ELF and VLF
waves radiated by electric power systems at the harmonic
frequencies of 50 or 60 Hz. Here we show for the first
time large scale MLR observed simultaneously on
ground and on board a low altitude satellite which is
flying over the same zone.

Description: To improve the boiler drum level control system of a power plant, the three challenging issues encountered include (1)
effect of ‘‘false water level’’, (2) controller parameter mismatches due to variant working conditions and (3) signal noise
caused by uncertainties of drum level. In this paper, based on analyses of the drum level signal, an adaptive derivative
action is presented to monitor steam flow, and thus, the effect of ‘‘false water level’’ is weakened. The uncertainties of
parameter mismatches and noise are predicted by developing a Grey predictor based algorithm (GPBA). In order to
resolve the three problems and further control performance, an adaptive technique is combined with the GPBA to develop
an adaptive Grey predictor based method. Finally, concrete simulations give that the proposed method has obvious superiority
over conventional methods.

Description: 数字式测光表，测量亮度 （外国人设计的）
在照度仪通常是用来测量照明。光照是如何光通量水平是一个面积下降。光通量是可见的组件，它是在辐射通量（光功率）以人眼的相对灵敏度分歧可见光谱定义。这意味着照度很好适合人眼的感觉从光的水平。-The Lux Meter is usually used to measure illumination. The illumination is how level of luminous flux is falling on a surface area. The luminous flux is visible component that is defined in radiant flux (light power) divided by relative sensitivity of human eyes over the visible spectrum. This means the Lux is well fit to light level from sense of human eyes.

Description: Energy and Power Spectra
It is frequently useful to study the distribution and power of a signal in the
frequency domain. For example, we may wish to have estimates for how the
power in a signal is distributed with frequency, so that we can quantitatively
state how much power is in a particular band of interest relative to other fre-
quencies. Given a power spectral density function, the power is then given by
the integral of the function over the band of interest.
