*Prepared in the Program Division, B u reau of Employment Security. D U R I N G 1946, employers subject to State unemployment insurance laws were taxed at an estimated average rate of 1.4 percent of taxable pay rolls (table l ) 1 —the lowest average rate since the first year of the program (1936) when the Federal tax rate was only 1 percent. The 1.4percent revenue rate is expected to yield $828...

The restriction of Pipe, a potential glycosaminoglycan-modifying enzyme, to ventral follicle cells of the egg chamber is essential for dorsoventral axis formation in the Drosophila embryo. pipe repression depends on the TGFalpha-like ligand Gurken, which activates the Drosophila EGF receptor in dorsal follicle cells. An analysis of Raf mutant clones shows that EGF signalling is required cell-au...

Several literatures presented automated systems for detecting or classifying sewer pipe defects based on morphological features of pipe defects. In those automated systems, however, the morphologies of the darker center or some uncertain objects on CCTV images are also segmented and become noises while morphology-based pipe defect segmentation is implemented. In this paper, the morphology-based...

CRA-lined pipelines, i.e. pipes with an inner pipe of a corrosion resistant alloy inside of a ferritic steel pipe carrying the hoop stress, pose a challenge to inspect with conventional in-line inspection technologies. Existing UT technology is not able to inspect through the interface of a CRA and a ferritic steel component. Additionally, current MFL technology is not able to sufficiently magn...

To evolve structured programs we introduce H-PIPE, a hierarchical extension of Probabilistic Incremental Program Evolution (PIPE). Structure is induced by \hierarchi-cal instructions" (HIs) limited to top-level, structuring program parts. \Skip nodes" (SNs) allow for switching program parts on and oo. They facilitate synthesis of certain structured programs. In our experiments H-PIPE outperform...

an important issue in power generation and petrochemical industries is the monitoring of pipe wall thickness and corrosion/erosion rate. the pipes are usually subject to erosive and/or corrosive environments and any failure could be catastrophic. while periodic manual ultrasonic thickness measurement is the common practice in many industries, in certain cases, where higher accuracies are requir...

Pipe dreams represent permutations pictorially as a series of crossing pipes. Recent applications of pipe dreams include the calculation of Schubert polynomials, fillings of moon polyominoes, and in the combinatorics of antidiagonal simplicial complexes. These applications associate pipe dreams to words of elementary symmetric transpositions via a canonical mapping. However, this canonical mapp...

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...
