This article proposes a multidisciplinary design and optimization （MDO） strategy for the conceptual design of a multistage ground-based interceptor （GBI） using hybrid optimization algorithm, which associates genetic algorithm （GA） as a global optimizer with sequential quadratic programming （SQP） as a local optimizer. The interceptor is comprised of a three-stage solid propulsion system for an exoatmospheric boost phase intercept （BPI）. The interceptor＇s duty is to deliver a kinetic kill vehicle （KKV） to the optimal position in space to accomplish the mission of intercept. The modules for propulsion, aerodynamics, mass properties and flight dynamics are integrated to produce a high fidelity model of the entire vehicle. The propulsion module com- prises of solid rocket motor （SRM） grain design, nozzle geometry design and performance prediction analysis. Internal ballistics and performance prediction parameters are calculated by using lumped parameter method. The design objective is to minimize the gross lift off mass （GLOM） of the interceptor under the mission constraints and performance objectives. The proposed design and optimization methodology provide designers with an efficient and powerful approach in computation during designing interceptor systems.

This paper presents an integrated fuzzy controller design approach to synchronize a dis- similar redundant actuation system of a hydraulic actuator （HA） and an electro-hydrostatic actu- ator （EHA） with system uncertainties and disturbances. The motion synchronous control system consists of a trajectory generator, an individual position controller for each actuator, and a fuzzy force tracking controller （FFTC） for both actuators. The trajectory generator provides the desired motion dynamics and designing parameters of the trajectory which are taken according to the dynamic characteristics of the EHA. The position controller consists of a feed-forward controller and a fuzzy position tracking controller （FPTC） and acts as a decoupled controller, improving posi- tion tracking performance with the help of the feed-forward controller and the FPTC. The FFTC acts as a coupled controller and takes into account the inherent coupling effect. The simulation results show that the proposed controller not only eliminates initial force fighting by synchronizing the two actuators, but also improves disturbance rejection performance.

Grain design is essentially filling a prescribed volume （chamber case） with a certain shape of propellant so as to ensure mission requirements. An infinite number of possibilities exist, covering from two dimensional to three dimensional grain designs. Accurate calculation of grain geometrical properties plays a vital role in performance prediction. In this paper a methodology has been presented for designing 3D grain configuration for Solid Rocket Motors （SRMs）. The design process involves parametric modeling of the geometry in CAD software through dynamic variables that define the complex configuration. Initial geometry is defined in the form of a surface which defines the grain configuration. Grain bum back is achieved by making new surfaces at each web increment and calculating geometrical properties at each step. Geometrical calculations are based on volume and change in volume calculations. Models for Axisymetric and Finocyl grain configuration have been developed. Equilibrium pressure method is used to calculate the internal ballistics. The procedure adopted can be applied to any complex geometry in a relatively simple way for preliminary designing of grain configuration.

The aerodynamic design of a strategic weapon is of interest, especially when the radar signatures are included in the conceptual design phase. The basics of stealth configurations and stealth mechanisms for missiles are reviewed. The Radar Cross Sections （RCS） of some generic missiles are predicted and compared to analyze the trade-offs involved between low RCS and aerodynamic performance. The consideration of RCS prediction in the conceptual design phase gives a quick insight into the stealth performance prior to detailed design.

Background: Treating infectious diseases (ID) is the priority of health systems. Traditional Persian medicine (TPM) has diagnostic and preventive comments in most diseases. Readout TPM gives opportunity to know the viewpoints of ancient Iranian scholars for using these opinions in treating ID. In this regard returning to TPM options and modalities can be useful at least as complementary method in treating ID. For understanding the concepts of ID in TPM first of all it is needed to trace ID in TPM and translate them into western medicine language which is the goal of this report. Methodology: This research includes 80 ID mentioned in TIBBE-AKBARI (one of Persian Medicine textbook) for rewriting and comparing with conventional medicine findings. Findings: The majority of clinical signs, symptoms and physical examinations of ID are comparable with modern medicine except the viewpoint of TPM about aetiology which is based on Akhlat and Mezaj theory. By considering no option for antibiotic therapy in ancients time so there is a completely different opinion in treating ID with modern medicine. Conclusion: IDs have different names in TPM and conventional medicine. In contrast to modern medicine in which micro-organism are as etiologic agents, Akhlat and Mezaj theory of TPM has main role for description of ID, the subject which must to be decoded. Although they have completely different opinions in treatment, but with regard to the increasing of antibiotic resistance issue, TPM treatment comments may be useful in future in ID as complementary method beside antibiotics.

为确定番茄斑萎病毒(TSWV)在山东烟草上的侵染,基于GenBank中已有的TSWV基因组序列设计该病毒特异性引物,通过总RNA提取,RT-PCR扩增,全基因组序列测定和拼接分析等,结果表明,山东临沂疑似病样中含有TSWV,该TSWV分离物具有3条RNA链,大小分别为8911、4773和2971bp,与国内已报道的其他TSWV分离物核酸序列同源性均在99.0%以上,蛋白氨基酸序列同源性均在98.0%以上。系统进化分析结果显示,该分离物与已报道的TSWV云南分离物聚类到同一分支中,推测山东烟区中的TSWV可能由云南烟区通过带毒介体的迁入而传入。该研究为山东烟区TSWV的发生流行溯源和该危险性病毒病的精准测报及防控提供科学依据。
