In this robot, achieve goals like precise tracking, stability and disturbance rejection are very important. In this paper, first the stages of modeling and simulating of laparoscopic robot will be discussed and the reasons for selecting the appropriate materials for different parts of proposed practical robot will be explained. Inverse dynamic controller with integral action is applied to improve the accuracy of tracking procedure for a surgical manipulator to track a specified reference signal in the presence of tremor that is modeled as constant bounded disturbance. Based on the disturbance rejection scheme, tracking controller is constructed which is asymptotically stabilizing in the sense of Lyapunov. It is shown that how under proper assumptions; the selected schemes succeed in achieving disturbance rejection at the input of a nonlinear system. Computer simulation results demonstrate that accurate trajectory tracking can be achieved by using the proposed controller.","PeriodicalId":383315,"journal":{"name":"2013 21st Iranian Conference on Electrical Engineering (ICEE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125272437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use the parasitic capacitances that appear at nodes between RF and LO stage for implementing π-Network. Circuit analysis and simulations show that the above technique is useful for wide-band applications. Simulation illustrates a power consumption of 4.97-mW at 1.8V, 3.61dB improvement in power conversion gain, and 3.38dB reduction in noise figure at the same power consumption with LO power of 0 dBm in comparison with the case when PDC technique is used only.

Several methods have been presented for torque ripple reduction in Switch Reluctance Motor (SRM). Some of them are based on changing the structure and the geometry of the motor. The other methods are done by utilizing control techniques. This paper introduces a 6 by 4 three-phase SRM as a normal mode structure which is designed by the SRM formula. The other modes of the SRM have been created by small changes in the dimensions of the normal mode. All of the modes are simulated by Finite Element Method (FEM). Next, the value of generated torque and torque ripple versus different rotor position are achieved. After that, the effect of the variations in dimensions of the SRM is studied on the value of the generated torque and torque ripple and according to this information the optimal structure is chosen. At the end, the optimal structure is constructed, tested in laboratory and the operational results are obtained.","PeriodicalId":383315,"journal":{"name":"2013 21st Iranian Conference on Electrical Engineering (ICEE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125992652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Production of multimedia content has increased in recent years and protection of copyright is highly demanded. Different watermarking methods have been proposed to satisfy the tradeoff between imperceptibility while maintaining a proper capacity for the embedded data. In general, transform domain watermarks, such as Contourlet-based methods, produce superior results as compared to spatial algorithms. Embedding in visually more complex regions of image would enhance imperceptibility of the method. In this paper we introduce a new complexity measure for this purpose. To show the effective of this criterion, we proposed a hybrid embedding scheme based on Contourlet Transform (CT) and Discrete Cosine Transform (DCT). This is done by analyzing complexities of image blocks in the CT domain to adaptively change the watermarking strength factor. This property enables our method to take advantage of all image blocks to elevate the embedding capacity while preserving imperceptibility. Experimental results show the efficiency of the proposed method to be higher than similar works in this domain.","PeriodicalId":383315,"journal":{"name":"2013 21st Iranian Conference on Electrical Engineering (ICEE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116539407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we have focused on optimum bidding of wind generation using utility theory, considering the risks which exist in wind generation. We proposed a new method to find the optimum bidding amount in different markets in such a way that maximum benefit and minimum risk could be achievable, simultaneously.

Each channel has different resonant cavity and filling analyte to selected hole causes independently shift in resonant wavelength. Also, this biosensor has high sensitivity and quality factor. The waveguide and cavities are respectively created by omitting a raw of water holes and one hole, respectively. This biosensor is consisted from hexagonal lattice of water holes in silicon on insulator slab.

The main aim of this paper is to determine optimal number and place of sectionalizers in distribution networks. By considering non-linear and non-differentiable nature of problem, using common methods to solve the problem is not possible. In this paper the optimization problem is solved by multi-objective genetic algorithm NSGAII to minimize installation cost of sectionalizers, simultaneously improving reliability indices, i.e. System Average Interruption Duration Index (SAIDI), Expected customer interruption cost (ECOST).
