Cancer is one of the major causes of death all over the globe and radiotherapy is considered one of its most effective treatment methods. Designing a radiotherapy treatment plan was done entirely manually in the past. RecentlyIntensity Modulated Radiation Therapy (IMRT) was introduced as a new technology with advanced medical equipmentin the recent years. IMRT provides the opportunity to delive...

Realizing and manipulating parity-time ($\mathcal{PT}$) symmetry in multidimensional systems are highly desirable for the exploration of nontrivial physics discovery exotic phenomena non-Hermitian systems. Finding that still have all-real spectra even if their Hamiltonians possess only partial $\mathcal{PT}$ has also attracted tremendous attention recent years. Here, we report experimental obse...

Research on Active Vibration Control System (AVCS) is being carried out to reduce structural vibrations caused by unwanted vibrations in many application areas such as in space, aircraft structures, satellites, automobiles and civil structures (bridges), particularly at low frequencies. The unwanted vibration may cause damage to the structure or degradation to the structure’s performance. The A...

As particle densities in accelerators and storage rings increase, instabilities arise that dilute emittance or, at worst, actually drive the beam out of the machine. Beam feedback systems can extend the intensity threshold of these instabilities. These systems have pushed the intensity limits of many accelerators beyond their design intensity and have become a necessity for present day operatio...

Abstract GaToroid, a novel gantry configuration for hadron therapy, is based on superconducting coils that generate toroidal magnetic field to deliver the beam tumour location. Designing complex GaToroid requires careful consideration of local optical effects. We present Python-based tool charged particle transport in electromagnetic fields. The code implements fast tracking arbitrary three-dim...

We are designing a synchrotron light source dedicated to medical applications including an intravenous coronary angiography for practical uses at a hospital. The synchrotron light source system is required to be compact for installation in a limited space of the hospital. The system is also required to be operated easily as medical diagnostic devices. For the energy subtraction coronary angiogr...

A Comb Drive Actuator is a basic actuation device of MEMS. MEMS applications often require large force, large displacement, low-power and energy-efficient actuators. Low power consumption is highly desirable not only for economic reasons, but also for heat generation considerations. In this paper, different types of structural design of Comb Drive Actuator that is Fixed-Fixed Flexure Beam, Crab...

In light of the recent European developments in ion beam therapy, there is a strong interest from the biomedical research community to have more access to clinically relevant beams. Beamtime for pre-clinical studies is currently very limited and a new dedicated facility would allow extensive research into the radiobiological mechanisms of ion beam radiation and the development of more refined t...

The next generations of vehicles will require data transmission rates in the order of terabytes per driving hour, to support advanced automotive services. This unprecedented amount of data to be exchanged goes beyond the capabilities of existing communication technologies for vehicular communication and calls for new solutions. A possible answer to this growing demand for ultra-high transmissio...

The rational use of lasers as sources radiation is also related to the development optical systems for conversion laser radiation. One ways convert its collimation, changing cross-section and divergence. This article presents a methodology designing two component reduce divergence beams. Ready-made elements were used, with which three different configurations created analyzed. design was develo...
