Autonomous aerial delivery system

It is rightly said that Robots are next generation citizen of the modern world. Advancements in robotics technology is increasing leaps and bounds which is making them flexible to do human like works more effectively without any rest. In this project we develop a autonomous aerial drone for delivery of products which will reduce manpower and also improve the quality of delivery. An autonomous aerial drone will be made, which is GPS linked and navigation enabled, which will fly off from the factory and deliver the product at the doorstep of the customer.

Assessment of artificial neural network performance and exponential regression in prediction of effective rainfall

According to the current water crisis and spend more than 94 percent of water in agriculture the mechanized irrigation systems, and revised the actual plant water estimation are needed it is facilitate to predict rainfall in the growing season. In the design of irrigation systems should be noted that the total rainfall occurred was not available for plant and part of the rainfall runoff and part of it penetrate to soil and only part of it that is called effective rainfall is able to disappear plant water stress and influence plant growing.

A study about personal learning environment building based on CMOOC concept

Under the background of education globalization and information technology, open education resources based on the concept of "open sharing" is the important trend of global education movement. MOOC is the new development of open education resources and breakthrough, that it embodies the transformation about the open education resources from the simple resources to curriculum and teaching, and this shift will inevitably impact on learner.

The reviews of Einstein's equation of logarithmic distribution platform and the process of changes in the speed range of the Karkheh river, Khuzestan province, Iran

In this study in order to evaluate the accuracy of the equation and its coefficient variation in addition to obtain flow characteristics in six sections and estimates of geometric parameters using the SPSS software HEC-RAS 4, sampled in many points of bed soil and were used in analysis. Results showed that the bed was rough and this roughness was only a function of the high slope of waterway and velocity gradient predicted by equation has good agreement with obtained gradient.

Study of modifications of the river physical specifications on muskingum coefficients, through employment of genetic algorithm

Sofar much research has been done of flood routing through Muskingum linear and non-linear model and genetic algorithm. Study of changed specifications of river such as waterway slope, width and length of the river, and the river bed which lead to determination of its roughness coefficient, and their impacts of flood hydrograph and finally on nonlinear model coefficients, are importance. In this research, effect of modifications of width and length of the ricer on coefficients of the Muskingum nonlinear model employing the genetic algorithm has been investigated.

Embedded system design for measurement of dielectric constant of conducting polymers at microwave frequencies

This paper deals with the design of an embedded system for acquiring the dielectric constant using microcontroller controlled stepper motor.  Dielectric parameters of general materials are measured manually by using x-band Microwave bench. These measurements are not much accurate when done manually.

Reduction of erythema after laser on rosacea by subthermal 448 khz monopolar radiofrequency

Excellent results are usually obtained when facial benign vascular alterations such as erythrosis and couperosis are treated with vascular laser (pulsed dye, KTP, Neodimiun-YAG) or with Intense Pulsed Light (IPL). However, the erythema occurring at hours or days after such treatment may hamper the patients’ ability to go back to their daily lives and increase the risk of adverse effects. The 448 kHz capacitive/resistive monopolar radiofrequency system is based on the subthermal electrical stimulation of tissues, enabling the restoration of ionic balance at cell level.

Characterization of a Cu2+-selective fluorescent probe based on benzoyl hydrazine derivative

A benzoyl hydrazine derivative was successfully characterized as Cu2+-selective fluorescent probe. Complexing with Cu2+ triggers a prominent fluorescence enhancement at 408 nm, accompanied by the change in the absorption spectrum in ethanol phase. With the optimized experimental conditions, the probe exhibited a dynamic response range for Cu2+ from 0.7 μM to 10 μM with a detection limit of 0.21 μM.

A simple and effective factorization procedure to determine total positivity of a matrix

A factorization procedure for a given totally positive (TP) matrix- a matrix with all positive minors - is introduced. The strategy is to reduce a column to corresponding column of the identity matrix. Factors so obtained are triangular matrices with constant row or column entries. Such matrices and their inverses with simple structures can be constructed using the entries of a given non-zero vector without any computations among the entries.

Assessment of standardization of sandcrete blocks production in lagos: case study of alimosho local government area, Lagos Nigeria

The paper assesses the quality of sandcrete blocks in some selected areas of Alimosho Local Government Area (LGA), the north eastern part of Lagos state, Nigeria. With the view of enhancing the quality of the production of sancrete blocks in the state. The study is hybrid in its methodological approach.
