this is business analytics question. (using gurobi) The days-off scheduling problem must be solved routinely by businesses that operate 6 or 7 days a week. Examples include hospitals, airlines, municipal transportation companies, and the postal service. The most common example is the (5,7)-cyclic staffing problem. The objective of it is to minimize the cost of assigning workers to a 7-day cyclic schedule so that 1) Sufficient workers are available every day. 2) Each person works 5 consecutive days and is idle to the remaining 2 days. Here is the table showing the cost of having an employee for each day and the number of employees required for each day. For example, the pattern that one works from Sunday to Thursday costs 90+604=330. Formulate and solve an integer programming problem to represent this problem. How many employees work Monday-Friday?.

we know that there is an OH group present in phenols. now, in ortho phenols here o-nitrophenols intramolecular bonding is possible due to the polar nature of OH bonds which can result in the formation of hydrogen bonds with the same molecule . this makes it water soluble and steam volatile which is not in the case of para-isomer. thus A mixture of p-nitrophenol and o-nitrophenol can be separated by steam distillation.

Liquid crystals (LCs) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal.[1] For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many different types of LC phases, which can be distinguished by their different optical properties (such as birefringence). When viewed under a microscope using a polarized light source, different liquid crystal phases will appear to have distinct textures. The contrasting areas in the textures correspond to domains where the LC molecules are oriented in different directions. Within a domain, however, the molecules are well ordered. LC materials may not always be in an LC phase (just as water may turn into ice or steam). Liquid crystals can be divided into thermotropic, lyotropic and metallotropic phases. Thermotropic and lyotropic LCs consist of organic molecules. Thermotropic LCs exhibit a phase transition into the LC phase as temperature is changed. Lyotropic LCs exhibit phase transitions as a function of both temperature and concentration of the LC molecules in a solvent (typically water). Metallotropic LCs are composed of both organic and inorganic molecules; their LC transition depends not only on temperature and concentration, but also on the inorganic-organic composition ratio.

The Data recovery is of two types … One method is by using a software that can recover files.There are certain benifits and risks by using this way. \'File System has file records and each file record is stored in Master File Table(MFT).MFT doesnt have file data but has only information about the file,which is used while retrieve the file. Each file and folder stored in File System has its entry in Master File Table. Even deleted files and folders also have there entry in Master File Table until it is reallocated to other file or folder. We also know that $BITMAP metadata file has information about allocation status of disk clusters. Using this information we have proposed the technique to recover deleted files from File System partition which is given below: Steps followed in deleted file recovery are: 1.Search Files MFT Entry 2. Process it’s $DATA attribute 3. If $DATA attribute is resident, file content is present in MFT Entry. Just copy it to external location to complete recovery process. 4. If $DATA attribute is non-resident, file’s contents are present in external cluster. Then parse the RunList present in the attribute. 5. Check if each cluster listed in Runlist is allocated or not. If all clusters have allocated status as 0, means that the files data is still present on disk. Therefore complete recovery is possible. Copy file’s contents to external location to complete recovery process. 6. If some clusters have allocated status as 1, then the partial recovery is possible. Copy file’s contents to external location with reallocated cluster’s values as zeros to complete partial recovery process. If all clusters have allocated status as 1, then the file’s contents are lost and recovery is impossible. The above technique can handle the file’s data which is fragmented across number of cluster runs so gives more granular results in recovery of deleted files. The technique does not require any external storage or use of sorting therefore can increase the performance in recovery process of deleted files. As we are discussing the file recovery through software the recovery software starts by trying to read and process the first copy of the info about files and folders. In some cases such as accidental file deletion, this is the only step where we can recover the file entirely If the first copy of the info about files and folders is severely damaged, the software scans the disk for the second copy of the info about files and folders. It also attempts to glean additional information about the folders and files structure that may be on the data part of the disk. Then, it processes all this information to reconstruct the original folders and file structure. If the file system on the disk isn\'t severely damaged, it is often possible to recover the entire file and folder structure. If the file system on the disk is severely damaged, this recovery method cannot recreate the entire folder structure. Then these files are stored in the unkonwn folders..

Quantum mechanics predicts the existence of what are usually called \'\'zero-point\'\' energies for the strong, the weak and the electromagnetic interactions, where \'\'zero-point\'\' refers to the energy of the system at temperature T=0, or the lowest quantized energy level of a quantum mechanical system. Although the term \'\'zero-point energy\'\' applies to all three of these interactions in nature, customarily (and hereafter in this article) it is used in reference only to the electromagnetic case. In conventional quantum physics, the origin of zero-point energy is the Heisenberg uncertainty principle, which states that, for a moving particle such as an electron, the more precisely one measures the position, the less exact the best possible measurement of its momentum (mass times velocity), and vice versa. The least possible uncertainty of position times momentum is specified by Planck\'s constant, h. A parallel uncertainty exists between measurements involving time and energy (and other so-called conjugate variables in quantum mechanics). This minimum uncertainty is not due to any correctable flaws in measurement, but rather reflects an intrinsic quantum fuzziness in the very nature of energy and matter springing from the wave nature of the various quantum fields. This leads to the concept of zero-point energy. Zero-point energy is the energy that remains when all other energy is removed from a system. This behaviour is demonstrated by, for example, liquid helium. As the temperature is lowered to absolute zero, helium remains a liquid, rather than freezing to a solid, owing to the irremovable zero-point energy of its atomic motions. (Increasing the pressure to 25 atmospheres will cause helium to freeze.) A harmonic oscillator is a useful conceptual tool in physics. Classically a harmonic oscillator, such as a mass on a spring, can always be brought to rest. However a quantum harmonic oscillator does not permit this. A residual motion will always remain due to the requirements of the Heisenberg uncertainty principle, resulting in a zero-point energy, equal to 1/2 hf, where f is the oscillation frequency. Electromagnetic radiation can be pictured as waves flowing through space at the speed of light. The waves are not waves of anything substantive, but are ripples in a state of a theoretically defined field. However these waves do carry energy (and momentum), and each wave has a specific direction, frequency and polarization state. Each wave represents a \'\'propagating mode of the electromagnetic field.\'\' Each mode is equivalent to a harmonic oscillator and is thus subject to the Heisenberg uncertainty principle. From this analogy, every mode of the field must have 1/2 hf as its average minimum energy. That is a tiny amount of energy in each mode, but the number of modes is enormous, and indeed increases per unit frequency interval as the square of the frequency. The spectral energy density is determined by the density of modes times the.
