Electrochemotherapy is an effective antitumor treatment employing locally applied high voltage electric pulses delivered through conductive electrodes to the tumor in combination with chemotherapeutic drugs. The efficiency of electrochemotherapy strongly depends on the local electric field distribution inside the target tissue. For successful therapy the entire target tissue has to be exposed t...

A focused electric spark is used as a non-contact acoustic source to excite stress waves in solids. The source consists of an electric spark source located at the near focus of an ellipsoidal reflector that focuses the acoustic disturbance generated by the spark source to the far focal point. Experimental studies using both contact and non-contact sensors indicate that the source has the capabi...

The most difficult aspect of rigid-body simulation is contact modeling. Two major subproblems of contact modeling are detecting contacts and computing contact forces. Although typically studied in isolation, these problems are tightly intertwined in simulation. This paper describes a method for fitting the pieces together. It gives an overview of the V-Clip collision detection algorithm, which ...

Lithium-ion (Li-ion) batteries are favored in hybrid-electric vehicles and electric vehicles for their outstanding power characteristics. In this paper the energy loss due to electrical contact resistance (ECR) at the interface of electrodes and currentcollector bars in Li-ion battery assemblies is investigated for the first time. ECR is a direct result of contact surface imperfections and acts...

Electrode contact impedance is a crucial factor in physiological measurements and can be an accuracy-limiting factor when performing electroencephalography and electrical impedance tomography. In this work, standard flat electrodes and micromachined multipoint spiked electrodes are characterized with a finite-element method electromagnetic solver and the dependence of the contact impedance on g...

Presbyopia is an age-related disorder where the lens of the eye hardens so that focusing on near objects becomes increasingly difficult. This complaint affects everyone over the age of 50. It is becoming progressively more relevant, as the average age of the global population continues to rise. Bifocal or varifocal spectacles are currently the best solution for those that require near and far v...

The paper presents an electro-thermal numerical model which can be used for the modelling and optimization of high currents dismountable contacts for dc current. The model is obtained by coupling of the electrokinetic field problem with the thermal field problem. The coupling is carried out by the source term of the differential equation which describes the thermal field. The model allows the c...
