However, any keyword search term that meets the characteristics of an ISBN and is entered with hyphens will be automatically concatenated by the search processor. This is a field useful to map catalogers. So, a record with a b P4 b C2 is searchable as , p4, and c2. There are three different year indexes in WorldCat. If a year in this index is cataloged with unknown characters, such as u, the "u" is replaced by zero's. Years that are shorter than four digits have leading zeros added.
To search year , enter The second index, the Year 2 of Publication index , is the second date field in the The year 2 index contains the ending year of a series, the original year of a reprinted work, and other specific year information. It is unlikely that users other than information professionals will be interested in using the second year index. Digits that were cataloged in this index as unknown are converted to nine. However, if all four digits are unknown, then it is converted to all zeros.
Years that are shorter than four digits have the leading zeros added. Note that the minimum value on the Year of Publication indexes for unbounded ranges is The Subject searches have many options. The Descriptor search includes only topical information. Additionally, there are indexes that search only the subject headings of a specific classification. The classifications are:. The Other subject headings index, includes all the subject headings indexed with the subfield 2 used to indicate what subject heading type was used.
To limit to one of these subject headings, AND any of these searches with the keyword search of the term indexed in the subfield 2. The library holdings group use attribute limits a search by the most widely held items.
Try using a rangeable search, such as 08, which would include all items held by libraries or more. Different types of material will have different high-end levels for searching. If you searching for highly technical material, 50 libraries holding the item would be a large number.
However, serial records and very popular works can be found in the rare "most held" group— The characters between the punctuation in the URL are the "words" that are searched for. The most distinct term in the string is the most useful on which to search. All the stopwords apply to this index, plus two additional stopwords, "http" and "https". Document Type is defining the primary document type of the record. Material Type includes all the document types, including primary and additional information, so that all records that include that document type information is included.
So while searching "rec" in the document type index is only sound records that have been cataloged with that as it's primary type, the same term in the material type index will also pull up items that include sound records, including attached material.
While all the values indexed in document type are also indexed in the material type index, some search terms in the document type index are different in the material type index These codes are described below. Material Type data is based on information in the Leader, , , , and looking for terms in specific parts of the record.

The ISBN is indexed as the data is indexed, without hyphens.

ISBNs use 7 remove and concatenate all punctuation including hyphens. However, a search can be entered with hyphens and get the appropriate ISBN records. Powder Mixed Electrical Discharge Machining is relatively a new development in the direction of enhancement of process capabilities of EDM.
The nickel-based alloys can be machined by conventional machining methods like turning but with specific cutting conditions of speed feed and depth of cut. The resulting tool wear is abnormal thereby increasing cost of machining.
EDM has been frequently used for providing slots in low machinability materials and difficult to cut materials like super alloys. One way is to use some metallic powders in dielectric fluid of EDM. The present work is also in the same direction.
Two main parameters related to powder addition have been taken and detailed experimental study has been conducted. The average grain size of Si powder particles and their concentration are taken as input parameters. Final SF, surface profiles and SEM photographs have been obtained at various combinations of the input parameters. Abstract Removing noise from the original image is still a challenging research in image processing.
Generally there is no common enhancement approach for noise reduction. The speckle noise is commonly found in the ultrasound medical images. There are different filtering techniques based on statistical methods for the removal of speckle noise. The main objective of filter is to remove noise while retain as much as possible the important image detail and feature.
Ultrasonic imaging is a widely used medical imaging procedure because it is economical, comparatively safe, transferable and adaptable. But due speckle noise it is difficult to interpret image accurately and experienced radiologist can only interpret image. The existence of speckle is unattractive since it disgrace image quality and it affects the tasks of individual interpretation and diagnosis.
Speckle degrades spatial and contrast resolution and obscures the underlying anatomy. The main objective of this thesis was the selection of appropriate filter for removal of speckle in medical ultrasound images. A comparative study is made on the performance of the Lee filter, Kuan filter, Frost filter, SRAD filter, AD filter in removing the speckle from the image and in preserving the edges.
Finally an algorithm is developed which performs all the filtering techniques on the input image and the statistical parameters are calculated for the output images obtained from all the filters. These statistical parameters are compared, the images corresponding to the best statistical value are displayed along with the filter name and corresponding value of the statistical parameters.
These parameters are used to calculate the image quality of the output image obtained from above mentioned filters, based on the values of these parameters the performance of the filters in terms of speckle removal and edge preservation is discussed.
