Dynamic taint analysis(DTA) is to analyze execution paths that an attacker may use to exploit a system. Dynamic taint analysis is a method to analyze executable files by tracing information flow without source code. DTA marks certain inputs to program as tainted, and then propagates values operated with tainted inputs. Due to the increased popularity of dynamic taint analysis, there have been a few recent research approaches to provide a generalized tainting infrastructure. In this paper, we introduce some approaches of dynamic taint analysis, and analyze their approaches. Lam and Chiueh’s approach proposed a method that instruments code to perform taint marking and propagation. DYTAN considers three dimensions: taint source, propagation policies, taint sink. these dimensions make DYTAN to be more general framework for dynamic taint analysis. DTA++ proposes an idea to vanilla dynamic taint analysis that propagates additional taints along with targeted control dependencies. control dependency causes results of taint analysis to have decreased accuracies. To improve accuracies, DTA++ showed that data transformation containing implicit flows should propagate properly to avoid under-tainting.

Recently, learning based control is a popular topic on robotic applications. this paper presents a novel learning based intelligent control method which realizes the balance control of a statically unstable and dynamically stable robota two-wheeled self-balancing robot. the control strategy could be segmented into two levels: a learning based controller using Support Vector Regression approach as a high level and a traditional PD controller as a low level. Support Vector Regression is utilized to learn the mapping between robot's state data and corresponding actions from experiments by using the inclined angle and its angular speed as inputs and the wheels velocity of the robot needed to keep balance as outputs. And the low level PD controller makes sure the motors achieve the velocity value gained before. Experiments are taken to show that the control method is useful and efficient. Additionally, this paper presents a practice of learning based control.

To solve the problem of complex designing and time consuming for the design process of the PSRM, dynamic model of the PSRM is built and co-simulation of the PSRM is performed based on Ansoft/Maxwell and Ansoft/Simplorer in this paper. Taking a new type of PSRM as the research object,the configuration, principle, and mathematical model of the PSRM are clarified. Withthe Maxwell, the initial value of the PSRM is calculated and the performance of the PSRM is optimized. By the built optimization model of the PSRM, static and transient analysis of the PSRM are analyzed based on Maxwell 2D. Asymmetrical half-bridge power converter circuit and control circuit are established based on the Simplorer. Connecting Maxwell and Simplorer, the dynamic model of the PSRM is constituted. then, co-simulation of the PSRM is implemented. the simulation results show that the dynamic cosimulation model is able to regulate the phase currents distribution and output the corresponding propulsion force. the validity of the proposed dynamic model and co-simulation are verified.

Withthe development of the social economy, more and more appliances have been presented in a house. It comes out a problem that how to manage and controlthese increasing various appliances efficiently and conveniently so as to achieve more comfortable, security and healthy space at home. In this paper, a smart controlsystem base on the technologies of internet of things has been proposed to solve the above problem. the smart home controlsystem uses a smart central controller to set up a radio frequency 433 MHz wireless sensor and actuator network (WSAN). A series of control modules, such as switch modules, radio frequency control modules, have been developed in the WSAN to control directly all kinds of home appliances. Application servers, client computers, tablets or smart phones can communicate withthe smart central controller through a wireless router via a Wi-Fi interface. Since it has WSAN as the lower control layer, a appliance can be added into or withdrawn from the controlsystem very easily. the smart controlsystem embraces the functions of appliance monitor, control and management, home security, energy statistics and analysis.
