No one likes to wait long when the telephone is out of order. Maintaining customer telephones is a significant problem for telephone operating companies because delays in fixing troubles mean dissatisfied customers. Moreover, the high costs of maintenance adversely affect the profits of the telephone companies. Within NYNEX (a regional Bell operating company and the parent company of New York T...

A feasibility study was conducted to determine whether the sublanguage methodology of NLP could analyze and represent the vital information contained in trouble tickets’ ungrammatical text and to explore various knowledge mining approaches to render the data contained in these documents accessible for analysis and prediction. Experiments showed that the linguistic characteristics of trouble tic...

Background Nursing homes fill a vital role in our society — caring for an increasingly frail population, especially for the indigent. About 98,000 mostly elderly Californians are cared for in more than 1,100 freestanding skilled nursing facilities (SNFs) at any given time. And demand for skilled nursing services will increase as baby boomers approach retirement age. California’s age 65-and-over...

What are the symptoms? You may have any of the following: • Shortness of breath, trouble breathing, or fast breathing • Trouble doing normal activities, such as exercising, playing sports, or doing chores that involve lifting • Trouble talking • Fingers or lips turning blue or gray • A peak flow rate (how fast you can blow air out of your lungs) less than 80 percent of your personal best • Tigh...

We study the structure of the phase space in Hořava-Lifshitz theory. With the constraints derived from the action, the phase space is described by five fields, thus there is a lack of canonical structure. The Poisson brackets of the Hamiltonian density do not form a closed structure, resulting in many new constraints. Taking these new constraints into account, it appears that there is no degree...

Comments on Van den Berg, et al. Toxic equivalency factors (TEFs) for PCBs, PCDDs, PCDFs for humans and wildlife. Environ Health Perspect 106:775-792 (1998)

An argument is presented for the inconsistency of black hole remnants which store the information which falls into black holes. Unlike previous arguments it is not concerned with a possible divergence in the rate of pair production. It is argued that the existence of remnants in the thermal atmosphere of Rindler space will drive the renormalized Newton constant to zero. PACS categories: 04.70.D...

The Inversion Problem Our standard modeling and control concepts and techniques include linear convolution models and various transform techniques (the Laplace transform, the Z-transform, the bilateral Laplace transform, the bilateral Z-transform, the continuous Fourier transform, and the discrete Fourier transform). In fact, these techniques form the basis of the broad areas of circuits, commu...
