In this paper, the absorbent carryover effect in a designed counter-flow enthalpy exchanger is investigated. In a built prototype of the liquid desiccant dehumidifier, air and the absorbent solution are in contact and flow through a packed multi-channel polymer tower in a counter-flow pattern. To avoid the absorbent carryover, the tower is equipped with an eliminator. Experimental measurements ...

Teleo-reactive programs and the triple tower architecture have been proposed as a framework for linking perception and action in agents. The triple tower architecture continually updates the agent’s knowledge of the world and evokes actions according to teleo-reactive control structures. This paper uses block stacking problems to demonstrate how genetic programming may be used to evolve hierarc...

This note describes a study of the maximum tower energies expected in the CMS HB & HE detectors from the QCD production of 2 jets at the LHC. This study shows that the maximum tower for the expected lifetime of CMS at the LHC should never exceed 3.5 TeV in any compartment of the barrel or endcap hadron calorimeter. ) email address [email protected]

By field investigation, it is found that the lower section of transmission tower body is the critical position for insuring tower’s integral stability under strong wind. For improving tower’s wind-resistant performance, the scheme of adding diaphragms at mid-height of diagonal members in lower tower body was proposed and its static effectiveness was researched by static loading tests. Taking th...

The cardiovascular system is a complex arrangement of hydraulic, yet living, components. The complexity of this system may make it difficult for students to see the "forest" instead of the "trees." To better explain the dynamics of cardiovascular function and control, an analogy has been drawn to the operation of a city water supply. In cities that use a water tower, fresh water is pumped up in...

Ecosystem fluxes of energy, water, and CO2 result in spatial and temporal variations in atmospheric properties. In principle, these variations can be used to quantify the fluxes through inverse modelling of atmospheric transport, and can improve the understanding of processes and falsifiability of models. We investigated the influence of ecosystem fluxes on atmospheric CO2 in the vicinity of th...

The complete spectrum of D = 6, N = 4b supergravity with n tensor multiplets compactified on AdS 3 × S 3 is determined. The D = 6 theory obtained from the K 3 compactification of Type IIB string requires that n = 21, but we let n be arbitrary. The superalgebra that underlies the symmetry of the resulting supergravity theory in AdS 3 coupled to matter is SU (1, 1|2) L × SU (1, 1|2) R. The theory...

In the aftermath of a flood, fire ants, Solenopsis invicta, cluster into temporary encampments. The encampments can contain hundreds of thousands of ants and reach over 30 ants high. How do ants build such tall structures without being crushed? In this combined experimental and theoretical study, we investigate the shape and rate of construction of ant towers around a central support. The tower...
