The compactness of transceiver is obtained because amplitude modulation or demodulation mechanism is inherent in one oscillator circuit. With injection locking property, frequency and phase of the oscillator is identical to that of the transmitted carrier. Based on time varying force function which is an AM signal, coherent demodulation is taken place. In laboratory experiment, the Colpitts oscillator at UHF band is employed where experimental results agree well with the proposed principle.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131587703","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}

A Sliding Mode Controller (SMC) was employed to control roll angle of the carrier, which is the most critical degree-of-freedom (DOF) to stabilize the carrier. Simulation results show good performance of the proposed controller, which can bring the roll angle to the setpoint quickly with a critical damp response. A comparison between open-loop and SMC was also conducted, the result of which ensures the effectiveness of the algorithm. A carrier testbed equipped with a digital gyroscope as the attitude sensor and trolling motors as the actuator, was constructed to test and validate the possibility and performance of the propose stabilization system.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122765511","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}

Due to the robots' small sizes, nearby vehicles that are prevalent especially in highly populated area could significantly attenuate robot communication signals. Via a linear regression of experimental results, a new mathematical expression predicting average vehicle-induced signal attenuation (in dB) as a linear function of a number of vehicles is derived. An example scenario about an outdoor casualty-search throughout a university campus by a small wirelessly-controlled robot that are capable of placing signal-relays to enlarge its operational area is provided. It is found that by taking into account of vehicle-induced signal attenuation, the robot could have sufficient wireless communication coverage to avoid failing to search for casualties in the crowded area where classroom buildings and office buildings are located.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125496291","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}

Commercial-off-the-shelf systems can be too expensive to implement during research and development phase. With a simple framework, we develop an in-house prototype of data collecting unit (DCU) and a base unit to manage transmitted rocket data. The DCU acts both as a wireless receiver and data storage. It can also transmit data upon request. A base unit sends a command to control DCUs during data retrieval process. Putting DCUs at an appropriate distance, we can effectively receive all transmitted data. It is evident that DCUs located at 2.5 km apart along the flight path have a combined high percentage of reception performance.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128244866","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}

Gunshot noise detection is required in a wide area of surveillance, security and defense (military applications). Recently, Gunshot and impulsive sound detection has relied on methods from the area of speech processing. Unfortunately, intensive computations is required in order to detect gunshot under noisy environment for those methods. In this work, we proposed a simple gunshot detection procedure based the signal in ZP domain (ZP signal) which is obtained by taking IDFT of the path power of a spectral amplitude. Since the energy concentration of gunshot signal is widely distributed on the time axis in ZP domain. On the other hand, the energy of wideband noise ZP signal is concentrated around the origin in ZP domain. Thus we can detect gunshot noise, because the energy concentration would stand out over other noise through the observation segments. Simulation result has proved its efficiency as a gunshot detection algorithm even in a noisy environment.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124318667","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}

Dynamic environment of broadcast encryption needs to support conditions which someone can join a group, members of a group can leave a group, a group can join other groups, and a group can be separated into smaller groups dynamically. In this paper, we propose a dynamic broadcast encryption scheme based on braid groups cryptosystem, which is an alternative method in the public key cryptosystem and can reduce the computational cost. Join, leave, merge, and partition protocols are stated in our scheme to deal with dynamic environment. Our scheme has some advantages over the scheme using symmetric group key in that the sender can be someone inside or outside the group and it gets rid of the problem in distributing a secret key.","PeriodicalId":311885,"journal":{"name":"2015 Asian Conference on Defence Technology (ACDT)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127759886","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}
