A mathematical programming problem is proposed for form-finding of cable domes. The optimality conditions of the problem are derived to guarantee that the optimal solution coincides with the self-equilibrium configuration of the cable dome with specified member axial forces. The number of independent axial forces is investigated under the geometrical constraints as well as equilibrium condition...

In this dissertation, we consider the downstream bandwidth management in the context of emerging DOCSIS-based cable networks. The latest DOCSIS 3.1 standard for cable access networks represents a significant change to cable networks. For downstream, the current 6 MHz channel size is replaced by a much larger 192 MHz channel which potentially can provide data rates up to 10 Gbps. Further, the cu...

In the referenced paper [ 11, the author examines the stability of the planar, linear response of a suspended cable subjected to harmonic axial loading. The study is motivated by a desire to understand the dynamic stability of cables employed in structures such as cablestayed bridges or guy-towers. In these applications, the harmonic axial load derives from the dynamic reaction of the structure...

Graphene deposited over a trench has been studied in the context of nanomechanical resonators, where experiments indicate adhesion of the graphene sheet to the trench boundary and sidewalls leads to self-tensioning; however, this adhesion is not well understood. We use molecular dynamics to simulate graphene deposited on a trench and study how adhesion to the sidewalls depends on substrate inte...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

Although much effort has been devoted in the last decade to solve the problem of synthesizing the frequency dependent transformation matrix in unbalanced multiphase cable system, we believe the best solution is to completely eliminate the necessity of the frequency dependent transformation matrix. This paper presents advances in the development of a new cable model (zCable) which splits the rep...

We present a lateral trench gate SOI-LDMOSFET that uses narrow trenches as channels. The lateral trench gate, which allows the channel current to flow laterally on the trench side walls, decreases its on-resistance because it increases the current spreading area of the device. The specific on-resistance ðRspÞ strongly depends on the trench depth, which affects the channel area on the side wall ...

The changes of the seabed environment caused by a natural disaster or human activities dramatically affect the life span of the subsea buried cable. It is essential to track the cable route in order to inspect the condition of the buried cable and protect its surviving seabed environment. The magnetic sensor is instrumental in guiding the remotely-operated vehicle (ROV) to track and inspect the...

We consider a generalization of the connected facility location problem where the clients must be connected to the open facilities via shared capacitated (tree) networks instead of independent shortest paths. This problem arises in the planning of fiber optic telecommunication access networks, for example. Given a set of clients with positive demands, a set of potential facilities with opening ...
