When you sharpen an image, increase magni cation to 100 percent and pay careful attention to the edges of objects in the images. If you notice any bright spots (halos) or colored specks, you ve over-sharpened the image. Reduce the amount of sharpening until the halos disappear.

a = a + b; // add two three_d objects - no conversion cout << a; return 0; } // displays 3, 5, 7

The base class constraint enables you to specify a base class that a type argument must inherit. A base class constraint serves two important purposes. First, it lets you use the members of the base class specified by the constraint within the generic class. For example, you can call a method or use a property of the base class. Without a base class constraint, the compiler has no way to know what type of members a type argument might have. By supplying a base class constraint, you are letting the compiler know that all type arguments will have the members defined by that base class. The second purpose of a base class constraint is to ensure that only type arguments that support the specified base class are used. This means that for any given base class constraint, the type argument must be either the base class, itself, or a class derived from that base class. If you attempt to use a type argument that does not match or inherit the specified base class, a compile-time error will result.

C# contains two general categories of built-in data types: value types and reference types. The difference between the two types is what a variable contains. For a value type, a variable holds an actual value, such 3.1416 or 212. For a reference type, a variable holds a reference to the value. The most commonly used reference type is the class, and a discussion of classes and reference types is deferred until later in this book. The value types are described here. At the core of C# are the 13 value types shown in Table 3-1. Collectively, these are referred to as the simple types. They are called simple types because they consist of a single value. (In other words, they are not a composite of two or more values.) They form the foundation of C# s type system, providing the basic, low-level data elements upon which a program operates. The simple types are also sometimes referred to as primitive types.

Solution Let the q s and b s be the angles for each portion shown. Note that for velocity and acceleration one should multiply values by w and w2, respectively, and the bound ary conditions are y(0) = 0, y(0) = 0, y(b4) = 0, and y(b4) = total rise h. Use basic trigonometric relationships for

1. Site access: Adequate access to the site shall be provided for trucks to deliver riprap. 2. Right-of-way: Construction easements and right-of-way access may be required for the duration of construction. 3. Detours: Detour, lane closure, or nighttime work may be necessary. Coordination with traf c control would be required. 4. Emergency vehicles and school bus services should not be affected by lane closures. 5. Utilities: Relocation of any utilities at the sides of an abutment or a pier may be necessary for the duration of construction. Coordination with utility companies would be required.

To design a moderately temperature stable collector feedback Class A or AB amplifier for HF, VHF, UHF and above (Fig. 3.82):

existing HVAC wiring comes through. However, just because the wiring is going to pop out of the same hole doesn t mean it has to start in the same location. The HVAC wiring in our own Smart Home was difficult to get at, simply by virtue of its placement. As such, it would have been more difficult to feed the new cabling through the existing hole. To ameliorate this problem, we simply drilled another hole next to the HVAC wiring. This allowed us to be able to send the fish tape through and connect the cabling, then pull it up to the living room. Naturally, your own home probably won t fit this particular solution; however, the point is to try and make your work as easy on yourself as possible.

Developer s challenge Why would you want to acquiesce rather than be honest Developer s follow-on response If the Two gives you a reason that makes sense to you, say: It sounds as though you re convinced this is the best choice, but let me ask you this: Are there alternatives for you to consider other than either acquiescing or confronting this person If the Two realizes that this is not a productive action to take, say: It s great that you realize this is not truly in your best interests. Let s discuss other alternatives and their potential positive and negative consequences.

The enrollment process essentially introduces a person to the authentication system. From a technical standpoint, we enroll Cathy in the system simply by providing a verifier associated with her. The exact procedure depends on the authentication factors being used as well as the organization s security concerns. Organizations with high security concerns will likely require a trusted administrator to participate in Cathy s enrollment, even though this increases administrative costs. Many organizations are willing to automate the enrollment process as much as possible, and this leads to self-enrollment systems. In a typical self-enrollment system, the user will enroll on a web page on the organization s internal network. If Cathy self-enrolls, for example, she visits the specified page and enters some identifying information, such as her employee number, so the system enrolls the correct person. Usually, she must also provide some additional personal information that the organization already has on file; this information is used to further authenticate her identity. Once Cathy has been identified and authenticated, the system establishes the correct verifier. If the system uses passwords, it may either generate one and tell it to Cathy, or it may prompt her to enter a password of her own choosing. If the system uses password tokens, smart cards, or other physical devices, Cathy must have the device in her possession to proceed. To self-enroll a secret-key device, such as a password token, Cathy typically must type in the device s serial number. When the device vendor delivers a number of tokens to a customer, it generally provides a confidential list of serial numbers along with the corresponding base secrets. An administrator installs this list in the authentication server so that the server can retrieve the correct base secret when enrolling a new device. If Cathy is self-enrolling with a public-key device, such as a smart card or a USB token, she must generally self-enroll at a workstation that has a reader for the card or token. When she plugs in the device and enrolls, the workstation retrieves her public key from the device. Since the data is a public key, there is no serious risk in retrieving it and transmitting it. Similarly, Cathy could self-enroll with a biometric system as long as she enrolls at a workstation that has the appropriate biometric reader. She would still have to provide one or more biometric readings to create her verifier, but the self-enrollment system would associate that verifier with Cathy s user record. A problem with unsupervised self-enrollment is that Henry might try to enroll himself as Cathy in a form of ultimate masquerade, using her identity and his biometrics. For this reason, self-enrollment is not as secure as supervised enrollment.
