hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...

Pavement maintenance and rehabilitation have been neglected in Nigeria for a very long time and has resulted to maintenance backlog. Design agencies in Nigeria still use California Bearing Ratio (CBR), even though the method is outdated. An introduction of Dynamic Cone Penetration Test (DCPT) was pertinent, even though the method is relatively old in some developed countries, it has not gain mu...

the paper presents a mathematical base modeling combined to modified-winding -function-approach (mwfa) for eccentricity fault detection of a round-rotor synchronous machine. for this aim, a 6-pole machine is considered, and the machine inductances are computed by mwfa in healthy and also under eccentricity fault. a numerical discrete-time method has been proposed to machine modeling in voltage-...

A set of suitable parameter values is crucial in discrete element method (DEM) simulations. As a non-spherical particle, the coefficients rolling friction between maize seed particles and boundary are hard to measure directly must be obtained by calibration. In this paper, taking three representative varieties as research objects, necessity for accurate calibration boundaries investigated. Subs...

Millions of dollars are spent each year to replace decayed marine piling. The primary avenue of decay infection is through the ends where untreated wood is exposed after piles are cut off. Thus, several fungicides were evaluated for their ability to protect the top cutoff end of creosoted Douglas-fir piles from decay. Supple­ mentary treatment with a 20 percent ammonium bi­ fluoride solution or...

In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256-bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers is S-box or logical operation, which has been well studied about security. It is a strong feature of the cip...

In this paper, the dynamic analysis of mental sweating for sound stimulus of a few tens of eccrine sweat glands is performed by the time-sequential piled-up en-face optical coherence tomography (OCT) images with the frame spacing of 3.3 sec. In the experiment, the amount of excess sweat can be evaluated simultaneously for a few tens of sweat glands by piling up of all the en-face OCT images. St...

The wounding of sugarbeet (Beta vulgaris L.) roots by harvesting and piling operations increases the demand for sucrolytic and glycolytic products for wound-healing processes. To determine if sucrolytic and glycolytic enzyme activities increase to meet this demand and to identify those activities that may be induced, the activities of the major sucrolytic enzymes and the major regulatory enzyme...

The technology follows a sequence of steps: 1) place a confinement template proximal to the disposal structure; 2) drive a primary confinement €I-beam and sheet piling proximal to and below the underground structure and contaminant plume; 3) inject a primary low-cost inorganic polymer below the contaminated geologic media; 4) injectMood the contaminant plume; 5) inject cements and sequestering ...
